I have problems with math questions here.  Are people just trying to get somebody else to do their homework?

go do your homework by yerself next time.\n\nBut becos im feeling nice today...\n\na triangle = 1 triangle , duh\na quadilateral can be divided into two triangles with vertices (points) all at the points of the quadilateral\n5 sided --> 3 triangles\n6 sided --> 4 triangles\n....\n12 sided --> 10 triangles\n1 triangle -->180 degrees\n10 triangles --> 1800 degrees

(# sides - 2) * 180 = sum of all the interior angles\n\n[(# sides - 2) * 180]/(# sides) = each interior angle if they're all congruent

Two angles whose sum is 90 degrees.

im a geo student, but i havent done proofs for a long time sorry. ok\n2. false, because squares are parallelograms with 4 congruent sides and 4 right angles, while kites have 2 pairs of congruent sides and only 1 pair of congruent angles that are NOT right angles\n3. false, because a rhombus is a parallelogram with 4 congruent sides, while a kite is any thing BUT a parallelogram. enuff said\n4. false, because kites are quadrilaterals with only two pairs of congruent sides, while the quadrilateral mentioned has 3 congruent sides\n5. false, for example- do trapezoids have 4 congruent sides, and 4 right angles, and is a parallelogram (characteristic of squares)? i think NOT\n6. read above- trapezoids are not parallelograms.

In any quadrilateral the sum of the angles is 360 degrees.  Its an axiom that has been proven.  It's similar to the axiom that all angles in a triangle add up to 180.\n\nNote: the pattern is:\n3 angles = 180\n4 angles = 360\n5 angles = 540\n6 angles = 720\n7 angles = 900\netc.\n\nAnother fact about parallelograms is that the opposite sides have the same lengths and the opposite angles have the same measure.  This also means that two consecutive angles will add up to 180 (since the other pair must be equal and the total must be 360, as noted before).

a rectangle, by definition is a quadrilateral where all four angles are right-angles, and an oblong is that which is right angled but not equilateral. I know its a bit obscure, but really, an oblong is an old fashioned term for a rectangle, without equilateral sides, if that's possible?!\n\nhope it helps

I need to do a drawing to answer this. Anyway, here are some usefull sites:\n\nhttp://www.bymath.com/studyguide/geo/sec/geo14a.htm\n\nThe parallel postulate. If parallel lines are cut by a transversal, then corresponding angles are congruent.

Pentagon = 5, decagon = 10, quadrilateral = 4, and heptagon = 7.

the four angles add up to 360 degrees

i don;t know all of them, but here are a few:\n-rectangle\n-square\n-rhombus\n-parallelogram\n-kite\n-trapezoid\n-and closed abject with four sides!\n-cyclic quaDrilateral     \n-cyclic-inscriptable \n\ncheck out the site dr. math for more info on quadrilaterals!

Congruent basically means the same. For math, this is probably regarding geometry. Two congruent triangles, when superimposed (placed on top of another) are exactly the same (rotation may be required).

A rectangle...equillateral means all equal sides, equiangular means all equal angles\n\nthe rectangle has all equal angles, 90 degress but teh sides are different, if the sides were the same it woudl be a square\n\na rhombus has equal sides but not necessarily equal angles\n\na parallelogram does not have to have equal angles or equal sides, it needs to have to sets of equal opposite angles and equal opposite sides\n\nhope this helps!!

equal number of sides and equal measure of angles\n\n\nor at least thats what i remember from geometry!

b. SAS\n\nSide-Angle-Side... two triangles with congruent angles with SAS relationship are equal triangles.

There are two angles formed wherever two sides of the hexagon meet. The angle inside the hexagon is 120 degrees and the angle outside the hexagon is 360 - 120 = 240 degrees. You can see this easily by placing a point at the center of the hexagon and connecting it to the 6 points where the edges of the hexagon meet. This forms 6 equilateral triangles and every one of the angles of the 6 triangles is 60 degrees (180/3). You can see that the angle inside the hexagon where 2 sides of the hexagon meet is equal to 2 of these 60 degree angles; hence 120 degrees. Draw it and you'll see it right away.
