Yes, because of the base angles theorem converse: If two angles in a triangle are congruent, then the sides opposite the angles are congruent.
The theorem states "If two angles are both supplementary and congruent, then they are right angles."
The Vertical Angles Theorem says that a pair of vertical angles are always congruent.
The isosceles triangle theorem states that if two sides of a triangle are congruent, the angles opposite of them are congruent. The converse of this theorem states that if two angles of a triangle are congruent, the sides that are opposite of them are congruent.
Yes, the base angles of an isosceles triangle are always congruent. An isosceles triangle commonly has two sides that are equal in length. The base angles are the angles opposite those two equal sides of the triangle. A geometric theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent. The converse is also true.
Yes, because an isosceles triangle has two equal base angles and two equal sides.
All right angles are the same.
if two angles are supplements of congruent angles, then the two angles are congruent.
The AA similarity theorem states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. This theorem is based on the Angle-Angle (AA) postulate, which states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
If the angles are congruent, they will be less than 360 degrees.
If the noncommon sides of two adjacent angles form a right angle, then the angles are complementary angles.
