The equilateral triangle :. Did this summary help you? Related Articles. The isosceles triangle I can NEVER remember how to spell isosceles has two sides that are the same length congruent and two angles that are the same size congruent. Angle size calculation refers to the use of geometrical laws and invariants to find out how many degrees an angle is.

My question is, how do I find the opposite direction of an angle, for example degree, how do I calculate the opposite direction in degrees?.

Most importantly, you learn that opposite angles are congruent angles, meaning they have the same angle degrees! To repeat, angles that are opposite, have. Small.

Is it a right angle? Coolmath privacy policy. For a rough approximation, use a protractor to estimate the angle by holding the protractor in front of you as you view the side of the house.

You can figure out what breed of angle you have by its measure. This article was co-authored by our trained team of editors and researchers who validated it for accuracy and comprehensiveness.

You can calculate the measure of an angle in a polygon if you know the shape of the polygon and the measure of its other angles or, in the case of a right triangle, if you know the measures of two of its sides. Regular polygons are those featuring same-size sides and -- subsequently -- same-size angles.
