No, An equilateral triangle has 3 congruent angles, an isosceles triangle has 2 congruent angles, a scalene triangle has no congruent angles.

The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.

It is called the mystery triangle

An equilateral triangle has 3 congruent angles that add up to 180 degrees.

An obtuse triangle must have two acute angles and these can be congruent.

If two angles in a triangle are congruent to two angles in another triangle, then the ______________ angles are also congruent.

A triangle with three congruent angles

equilateral triangle.

It is when there are four congruent angles and six congruent sides in a triangle.

In an isosceles triangle 2 sides are congruent and 2 angles are congruent. In an equilateral triangle all 3 sides are congruent and all 3 angles are congruent also.

The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.

yes, only the isosceles triangle has two congruent angles. But triangles don't need any congruent angles

A quadrilateral shape has four sides and four internal angles. A triangle has three sides and three internal angles. Therefore there is no such thing as a quadrilateral triangle.

no because if an scalene triangle had 2 congruent angles it wouldn't be a scalene it would be a isosceles triangle because an isosceles triangle is the only triangle with 2 congruent angles

Yes, because of the base angles theorem converse: If two angles in a triangle are congruent, then the sides opposite the angles are congruent.

No, a triangle and a rectangle are not congruent. Congruent means exactly the same size and shape. A triangle has 3 sides while a rectangle has four. A triangle's three angles always add up to 180 degrees where as a rectangle's four right angles always equal 360 degrees. They are not congruent- not even similar- at all.
