The number of triangles in a pyramid depends on the base of the pyramid. The triangle represents the relationship between two people. 5 The student, given information concerning the lengths of sides and/or measures of angles in triangles, will a) order the sides by length, given the angle measures; b) order the angles by degree measure, given the side lengths; Can you see if you can figure out how many triangles there are in the image below? You should count 8 medium triangles. Triangles that are not a classified as a right triangle require us to use different formulas. 1 large square with 4 large triangles (each using 4 small triangles), each large triangle not sharing any of its own small triangles with any of the other triangles: 4.
