identify all angles that are coterminal with each angle?
74508
Coterminal Angles are angles who share the same initial side and terminal sides. Finding coterminal angles is as simple as adding or subtracting 360° or 2π to each angle, depending on whether the given angle is in degrees or radians. There are an infinite number of coterminal angles that can be found.

In pre-calculus, you need to evaluate the six trig functions — sine, cosine, tangent, cosecant, secant, and cotangent — for a single angle on the unit circle. For each angle on the unit circle, three other angles have similar trig function values.

To find a positive and a negative angle coterminal with a given angle, you can add and subtract 360° if the angle is measured in degrees or 2π if the angle is measured in radians .

The complement of 37° is 53°. If you have a rectangle and you draw in the diagonals, then the two angles at each corner are adjacent complementary angles. Think of the letter "C" for "Corner" to remember complementary angles add up to 90°.

Knowing only angle-angle-angle (AAA) does not work because it can produce similar but not congruent triangles. When you're trying to determine if two triangles are congruent, there are 4 shortcuts that will work. Because there are 6 corresponding parts 3 angles and 3 sides, you don't need to know all of them.

If the diagonals of a parallelogram are equal, then show that it is a rectangular. so ∠ BAD and ∠ CDA are right angles as they are congruent and supplementary.

Compass points The four cardinal directions are north (N), east (E), south (S), west (W), at 90° angles on the compass rose. The four intercardinal (or ordinal) directions are formed by bisecting the angle of the cardinal directions: northeast (NE), southeast (SE), southwest (SW) and northwest (NW).
