If two sides of a triangle are equal in length to the third side, then the triangle is equilateral, and all angles are 60 degrees.
The congruent sides of an isosceles triangle are the two sides that are equal in length. These two sides are opposite the equal angles of the triangle. The third side, called the base, is not equal in length to the other two sides.
Translating a triangle by 2 units will not change the measures of the sides, angles, or any other properties of the triangle. Translation is a rigid transformation that moves the entire shape without distorting it.
Acute scalene triangle: A triangle with three sides of different lengths and all three angles less than 90 degrees. Acute isosceles triangle: A triangle with at least two sides of equal length and all three angles less than 90 degrees. Acute equilateral triangle: A triangle with three equal sides and all three angles measuring less than 60 degrees.
If two angle bisectors of a triangle are congruent, then the triangle is isosceles. This is because the angle bisectors of a triangle are concurrent and the angle bisectors of a triangle that are congruent divide the opposite sides of the triangle into two equal segments. So if two angle bisectors are congruent, the sides opposite those angles are also equal, making the triangle isosceles.
Yes, the diagonals of an isosceles triangle are congruent. This is because an isosceles triangle has two sides that are equal in length, which creates two congruent triangles when the diagonals are drawn.
