Complementary angles are those that add up to 90°
Thus all angles complementary to a given angle must all be the same angle (90° - the_given_angle), ie they are all congruent angles.
if two angles are supplements of the same angle (or of congruent angles), then the two angles are congruent.
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
congruent
Yes. The lower base angles are congruent. The upper base angles are congruent.
Angle Angle Side is a method one can use to prove that two triangles are congruent. Basically, if any two pairs of angles and the side between these angles are congruent, then the triangles are congruent as well.
ANSWERIf two angles are complementary to the same angle (or to two congruent angles), then the two angles are congruent.< means "Angle".Hypothesis:
A+
Complements are defined for angles, not trigonometric ratios of angles.
if two angles are supplements of the same angle (or of congruent angles), then the two angles are congruent.
Supplementary Congruency Theorem
The Angle Side Angle postulate( ASA) states that if two angles and the included angle of one triangle are congruent to two angles and the included side of another triangle, then these two triangles are congruent.
Congruent angles (or equivalent angles) have the same angle measure.
Two angles that are congruent have the same angle measurement.
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
angle bisectorangles bisector is the line that divides an angle into two congruent angles.
congruent
Yes. The lower base angles are congruent. The upper base angles are congruent.
