Chapter 1.1, Problem 52E

Determine the type of triangle represented if the lengths of its sides are: a a=1.5, b= 2 and c = 2.5 b a= 20, b= 21 and c = 29 c a=10, b= 12, and c =16 d a= 5, b= 7 and c = 9

Show that there is no triangle for which a=4 feet, b=14 feet, and A=60.

Classify as true or false: a If the midpoints of two sides of a triangle are joined, the triangle formed is similar to the original triangle. b Any two isosceles triangles are similar.
