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.
What else can I help you with?
An angle not congruent to the base angles of an isosceles triangle?
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
In an isosceles triangle the base angles are?
The base angles of an isosceles triangle are congruent.
If the base angles of a triangle are congruent then the triangle is isosceles?
It will be either isosceles or equilateral. It is equilateral if all of the angles are congruent.
What is the same about an isosceles triangle and an isosceles trapezoid?
In an isosceles triangle and an isosceles trapezoid, both base angles are congruent
Which statement about the base angles of an isosceles triangle is true?
The base angles are always congruent.
What angle is congruent in an isosceles triangle?
The two "base" angles.
Which two angles of isosceles triangle is congruent?
The two base angles are equal
If a triangle has two congruent angles is it isosceles?
Yes, because of the base angles theorem converse: If two angles in a triangle are congruent, then the sides opposite the angles are congruent.
How many congruent angles does a right isosceles triangle have?
It has 2 equal base angles
If two angles of a triangle are congruent then the sides opposite those angles are congruent by the converse to the Isosceles Triangle Theorem?
Yes, because an isosceles triangle has two equal base angles and two equal sides.
What does isosceles triangle look like?
An isosceles triangle has at least two equal sides and two equal angles An isosceles triangle has two or more congruent sides called legs. In an isosceles triangle with just two congruent sides, the angle formed by the legs is called the apex, and the other two angles, called base angles, are congruent. If the isosceles triangle has three congruent sides (AKA an equilateral triangle), then all three sides and angles are congruent, and there are no definitive base or vertex angles, besides...all of them.
