Triangles are geometric figures formed by three sides that, when joined together, form three internal angles, whose sum is 180°. The congruence between two triangles is that both have the same length in their corresponding sides and the same measures in their corresponding angles. There ...
We also have the SSS criterion, where the corresponding sides of both triangles must be in proportion. If we do not have the necessary information to prove the similarity of the two triangles, we must conclude that they are ...
In an equilateral triangle ABC, D is a point on side BC such that BD = 1/3 BC. Prove that 9AD2=7AB2 View Solution The perimeters of two, similar triangles ABC and PQR are 75 cm and 50 cm respectively. If the length of one side of the triangle PQR is 20 cm, then what is the...
In similar triangles ABC and DEF, corresponding sides AB and DE equal 15 and 12, respectively. If the perimeter of triangle ABC = 40, what is the perimeter of triangle DEF? The perimeter of a triangle is equal to 24 feet that has one side is b, the...

Are two right isosceles triangles always similar? One angle of an isosceles triangle measures 108 degrees. What other angles could be in that isosceles triangle? Can a right triangle be scalene? a. Classify the triangle given below by its sides and angles (Figur...
If the hypotenuse is 41 cm and the legs are 9 cm and 39 cm, does this form a right triangle? Triangle PQR is similar to triangle DEF, PQ = 4 cm, DE = 6 cm, P R = x 2 , D F = 24 x 2 What is the length of DF? Is it possible to hav...
Prove that if two right triangles have hypotenuses of equal length and an acute angle of one is equal to an acute angle of the other, then they are congruent Consider tirangles ABC and DEF. Side A is congruent to side F. Angle A is cong...
