Measure sides and angles of triangles to determine whether triangles are the same size and shape (congruent) or the same shape, but different size (similar).
Clarifications:
Relates to using properties of congruent and similar triangles. Student may use measuring tools, such as templates, protractors, and rulers. Student measures length of sides up to 12 inches and angles using 5° increments.

Standard:
Triangles : Identify and describe various kinds of triangles (right, acute, scalene, isosceles, etc.). Define and construct altitudes, medians, and bisectors, and triangles congruent to given triangles. Prove that triangles are congruent or similar and use properties of these triangles to solve problems involving lengths and areas. Relate geometry to algebra by using coordinate geometry to determine regularity, congruence, and similarity. Understand and apply the inequality theorems of triangles.
