Answer 2

Step-by-step explanation:

$\boxed{\tt{\red{answer}}}$

$\mapsto\tt{}$

An isosceles triangle is a triangle that: Has two congruent sides. Has congruent base angles. Has an altitude which: (1) meets the base at a right angle, (2) bisects the apex angle, and (3) splits the original isosceles triangle into two congruent halves.

$\mapsto\tt{}$

each interior angle of an equilateral triangle is equal to 60 degrees. The interior and exterior angle of any polygon add up to 180 degrees. In the case of the equilateral triangle, , the exterior angle, plus 60 equals 180. Subtracting 60 from both sides of this equation gives us a value of equal to 120.

$\mapsto\tt{}$

In a Euclidean space, the sum of angles of a triangle equals the straight angle (180 degrees, π radians, two right angles, or a half-turn). A triangle has three angles, one at each vertex, bounded by a pair of adjacent sides
