The document outlines various triangle formulas including the semi-perimeter and area calculations for different types of triangles such as equilateral, isosceles, and scalene. It explains how to calculate the area using base and height or by utilizing the sine of the angle between two sides. Additionally, it provides formulas for when the coordinates of the triangle's vertices are given.

TRIANGLE FORMULAS (sides are a, b , c and height h) SEMI PERIMETER(s) = (a+b+c/2) AREA OF TRIANGLE = ½(base*height) AREA OF TRIANGLE = ½[b*c*sin(angle b/w these sides) AREA OF EQILATERAL TRIANGLE = HEIGHT OF EQILATERAL TRIANGLE = AREA OF ISOSCELES TRIANGLE = a a a a a b a b c Equilateral triangle isosceles triangle scalene triangles h
