Because the base angles of an isosceles triangle are congruent, if one base angle is a right angle then both base angles must be right angles.
Q. What is a triangle with two congruent sides and two congruent angles?

Q. How do you prove two sides are congruent?
If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.
Q. What makes the two triangles congruent by SSS?
The SSS rule states that: If three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.
Q. Are all isosceles triangles congruent?
Not all isosceles right triangles are congruent. In order for two triangles to be congruent, they must have the exact same shape and the exact same…
Q. Can similar triangles be congruent?
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion . In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.
Q. How do you know if it’s an isosceles triangle?
Identifying isosceles triangles An isosceles triangle has two equal sides (or three, technically) and two equal angles (or three, technically). The equal sides are called legs, and the third side is the base. The two angles touching the base (which are congruent, or equal) are called base angles.
Q. How can you prove a triangle is a right triangle?
The converse of the Pythagorean Theorem is: If the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.
Q. How do you find the angles on a triangle?
The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. Another way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°.
