Webof the Isosceles Triangle Theorem: (1) A triangle is equilateral if and only if it is equiangular. (2) Each angle of an equilateral triangle has a degree measure of 60. The congruent sides of the triangle imply that all the angles are congruent. We can also use the converse of this, which is that three congruent angles imply three

WebAnswer: The length of the third side of the triangle is 7.63 units. Example 3: In triangle ABC, ∠C = 42° and ∠A = 33°, and the side opposite to angle C is 12.5 units. Find the length of the side of the triangle opposite to angle A. Solution: We have ∠C = 42° and ∠A = 33°, c = 12.5 units. We need to find the side 'a'.

WebNov 8, 2011 · If the measures of two angles of an isosceles triangle are 54 degrees and 63 degrees what is measure of the third angle? The total internal angles of a triangle always equal 180 degrees. Therefore, the third angle of this triangle must be 180 - 54 - 63 = 63. Since this value is the same as one of the stated sides, the triangle is indeed isosceles.
