two angles that are congruent and complementary? i dont really get math.?

a right angle triangle can be complmentary and so can 2 acute triangles, these two can also be congruent.

m<Z = 52\nThe three angles add to 180.\nm<X + m<Y + m<Z = 180\nThus,\nm<Y = 180 - 52 - 52\n= 76\nAlso, I assumed you meant that XY is congruent (or equal) to YZ.  Then m<X = m<Z.

ALL triangles are ALWAYS 180 degrees.\nIf a triangle is "right", that means that one angle is 90 degrees.....meaning that the other two angles have to also equel to 90 degrees.....\nComplimentary means two angles equeling 90 degrees.....therefore, both of the acute angles are compimentary because they have no choice in the matter

Complementary angles add up to 90 degrees.\nSupplementary angles add up to 180 degrees.\n\nJust think in alphabetical order: C comes before S, and 90 comes before 180.

A _______________ B\n... &#92;.................. ...............&#92;\n..... &#92;.................. ...............&#92;\n....... &#92;_______________&#92;\n...... D.................. ...............C\n\nLet ABCD be a quadrilateral with AB || DC and AB = DC\n\nDraw diagonal AC\n\nNow in Δs ABC, CDA\nAB = DC (Data)\n<BAC = <DCA ( Equal alternate angles, AB||DC)\nAC is common\nTherefore ΔABC ≡ ΔCDA (SAS property)\n\nTherefore < BCA = < DAC (Corresponding angles of congruent triangles are equal)\n\nTherefore BC||AD (alternate angles are equal)\n\nSo ABCD is a parallelogram as opposite sides are parallel

When  two  angles are combined to total 90°, they are referred to as complimentary angles. Supplementary  angles  form when two angles combine to total 180°

When two lines cross, 4 angles are formed.  Let p be the point of intersection and move around p counterclockwise.  Call the angles w x y and z.  Note that x and y are supplementary, since they join to make one of the two lines.  Similarly, y and z are supplementary, as they join to make the other line.  Thus x+y = 180° and y+z = 180°.  This means x = z.  These are called vertical angles, on opposite sides of p.  By the same reasoning, w and y are vertical angles, and are congruent. \nWhen presented with vertical angles, one measurement determines everything.  If w is 50° then so is y, while x and z are 130°.  If w = 90° then all four angles are right angles.  In this case the lines are said to be perpendicular.

There are three cases:\n1) Side-Side-Side (SSS)\n2) Side-Angle-Side (SAS)\n3) Angle-Side-Angle (ASA)\nNote that Angle-Angle-Angle (AAA) does not guarantee two triangles are equal (congruent).  It does guarantee that they are similar.\nAlso, Angle-Angle-Side (AAS) does not mean the triangles are congruent.

The sum of the angles of a rectangle is always 360 degrees. Four angles of 90 degrees each; you will always get 360 anyway you add them up. \n\nReminds me of 360 degrees in a circle. Full circle.

coterminal angles differ by 360 degrees (or 2pi)\nso add 2pi to pi/4 . . . [pi/4 + 8pi/4 = 9pi/4] -->because 2pi = 8pi/4\nand subtract 2pi. . .you can do it!\n\nanswer this: what is 2 + 1/4?\nand this:   what is 8/4 + 1/4

Depending on what you need to solve, you need two angles and a side, or two sides and an angle. Hit me with an E-Mail if you are stuck with something.\n\nkeptcompany@yahoo.com

All you have to use is the fact that for any triangle, the measures of the three interior angles add to 180 degrees.  So if you have Triangles ABC and DEF, then you know:\nangleABC + angleBAC + angleBCA = 180 degrees, and\nangleDEF + angleEDF + angleEFD = 180 degrees.\n\nIf two angles are congruent, then they have the same measure in degrees.  So, if angleABC is congruent to angleDEF, and angleBAC is congruent to angleEDF, then:\nangleABC = angleDEF, and\nangleBAC = angleEDF.\n\nUsing substitution:\nangleABC + angleBAC + angleBCA = angleDEF + angleEDF + angleEFD\nangleDEF + angleBAC + angleBCA = angleDEF + angleEDF + angleEFD\nangleDEF + angleEDF + angleBCA = angleDEF + angleEDF + angleEFD.\n\nthen simplify by subtracting (angleDEF + angleEDF) from both sides:\n\nangleBCA = angleEFD.\n\ntherefore, the third angles are congruent.

D.  The angles have to add up to 180.  If 2 of the angles are the same, then the 3rd has the same.  You have to get an enclosed side to be the same for the triangles to be congruent.

supplementary angles = angles whose sum is 180 ° or pi radiants.\n\nSo, pi - 11/12.

Well, Vanessa almost got it....the side opposite the 90 degree angle is the hypotenuse "C", the adjacent sides to the angle are "A" & "B". The correct formula is A squared plus B squared = C squared.\n\nor\n\nA^2 + B^2 = C^2\n\npi is an infinately long number about equal to  3.14

use the tangent ratio ( trig function ) or inverse tangent of (6/ (43/8)) OR iNV TANGENT (1.116) = 48.14 degrees and to get the other angle, just subtract it from 90 degrees or 41.86 degrees. hope it helps how I got it. go over the trig function or cohsahtoa rule

A pair of angles are supplementary if their respective measures sum to 180 degrees.\n\nYou would subtract an angle less than 180 to get it's supplement.
