Given Triangle ABC in the coordinate plane with endpoints at A(4,0), B(8, 2) and C(6, 6), give the endpoints of a triangle DEF that would be similar to Triangle ABC by a scale factor of 1/2.
Triangle DEF with D(2,0), E(4, 1), and F(3,3).
Given two complementary angles, ABC and CBD, where m(ABC) = 65, find the measure of angle CBD.
m(CBD) = 25

The reason why you know that a triangle with side lengths of 5.4”, 7.2” and 9” is definitely a right triangle.
What is because 5.4 squared + 7.2 squared = 9 squared ?
