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.
The measure of an exterior angle of a triangle is120 degrees the interior angles that are not adjacent to this exterior angle are congruent find the measure of the interior angles of the triangle?
They are all 60 degrees.
What is the measure of a base angle of an isosceles triangle if the measure of the vertex angle is 42 and two congruent sides each measure 21 units?
The length of the congruent sides makes no difference to the measured angles. Assuming the base angles are the congruent angles, then: angle = (180o - other_angle) ÷ 2 = (180o - 42o) ÷ 2 = 69o
Triangle with all angles congruent?
A triangle with all angles congruent are called equilateral. Each angle is 60 degrees.
Angles that have the same measure are?
Angles with the same angle measure are congruent.
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.
An equiangular triangle has three congruent angles What is the measure of each angle of an equiangular triangle?
Each angle is 60 degrees
The measure of an exterior angle of a triangle is120 degrees the interior angles that are not adjacent to this exterior angle are congruent find the measure of the interior angles of the triangle?
They are all 60 degrees.
If two angles have the same angle measure then they are said to be .?
Congruent angles (or equivalent angles) have the same angle measure.
What is the measure of a base angle of an isosceles triangle if the measure of the vertex angle is 42 and two congruent sides each measure 21 units?
The length of the congruent sides makes no difference to the measured angles. Assuming the base angles are the congruent angles, then: angle = (180o - other_angle) ÷ 2 = (180o - 42o) ÷ 2 = 69o
The measure of one angle or a triangle is 115 the other two angles are congruent what is the measure of each angle?
32.5 + 32.5 +115 =180
Triangle with all angles congruent?
A triangle with all angles congruent are called equilateral. Each angle is 60 degrees.
What is the Third angle theorem?
If two angles of one triangle are congruent to two angles of another triangle, then the third angles are also congruent.
What is Angle Side Angle?
If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.
Angles that have the same measure are?
Angles with the same angle measure are congruent.
A triangle containing 1 right angle and 2 congruent acute angles is called?
A triangle with 1 right angle and 2 congruent acute angles is both a right triangle and an isosceles triangle.
What angle is congruent in an isosceles triangle?
The two "base" angles.
