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.
Is the isosceles triangle is always a right triangle?
It usually is a right angle that represents an isosceles triangle but there are some cases that the right and left side are equal and the base is the one with an unequal length.
Can height and base be equal of right triangle?
Yes and it will have a 90 degree angle and two angles of 45 degrees. Such a triangle is called an isosceles right angle triangle.
The vertex angle of an isosceles triangle is twice as large as one of the base angles Find the measure of the vertex angle?
90 degrees. This is an isosceles right triangle, standing on its hypotenuse.
Why a triangle with a two 45 degrees angles is an isosceles triangle?
Because it has 2 equal base angles and 2 equal sides It is the only triangle that is both an isosceles and right angle triangle
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.
Is the isosceles triangle is always a right triangle?
It usually is a right angle that represents an isosceles triangle but there are some cases that the right and left side are equal and the base is the one with an unequal length.
What is the angle opposite the base angles of an isosceles triangle?
The third angle of an isosceles triangle doesn't have a name.
Can height and base be equal of right triangle?
Yes and it will have a 90 degree angle and two angles of 45 degrees. Such a triangle is called an isosceles right angle triangle.
The vertex angle of an isosceles triangle is twice as large as one of the base angles Find the measure of the vertex angle?
90 degrees. This is an isosceles right triangle, standing on its hypotenuse.
Can an isosceles triangle Always be a right triangle?
In an isosceles triangle, two angles, and therefore sides (Base Angle Theorem), are congruent. This does not mean that all isosceles triangles are also right triangles - there is only one (45, 45, 90 triangle).
Why a triangle with a two 45 degrees angles is an isosceles triangle?
Because it has 2 equal base angles and 2 equal sides It is the only triangle that is both an isosceles and right angle triangle
The angle opposite the base angles of an isosceles triangle?
Vertex angle
The angle opposite the base of an isosceles triangle?
O
What are 2 properties of an isosceles triangle?
-- An isosceles triangle has two equal sides. -- An isosceles triangle has two equal angles. -- An isosceles triangle has two equal interior-angle bisectors. -- The bisector of the vertex angle of an isosceles triangle is also the perpendicular bisector of the triangle's base.
Is it only in an isosceles triangle that the base angles are equal?
No. It need not be the base angles that are equal, it can be one of the base angles and the top angle (if the triangle is tipped over). Also, the base angle are equal in an equilateral triangle - although an equilateral triangle is a special kind of isosceles triangle.
What angle is congruent in an isosceles triangle?
The two "base" angles.
