WebN points on the side An equilateral triangle A, B, and C on each of its inner sides lies N=13 points. Find the number of all triangles whose vertices lie at given points on different sides. Area of a triangle Find the area of a … WebLike the 30°-60°-90° triangle, knowing one side length allows you to determine the lengths of the other sides of a 45°-45°-90° triangle. Angles: 45°: 45°: 90° Ratio of sides: 1:1:√ 2 Side lengths: a:a:c Given c= 5: a = c √ 2 = 5 √ 2 45°-45°-90° triangles can be used to evaluate trigonometric functions for multiples of π/4.
