5. Define the following types of triangles:
Right
Obtuse
Acute
Isosceles
Equilateral
Scalene
6. Given: An Equilateral Triangle
Side 1 = 4x + 5
Side 2 = 7x – 16 Side 3 = 3y + 3
Find the value of y, and the measures of the 3 angles
7. An exterior angle at A of ∆ABC measures 12x. If mLB = 7x – 2 and
mLC = 6x – 8, what is the value of x?
8. If you wanted to prove ABC = XYZ using the SAS postulate, name 3 parts
you would have to prove congruent.
9. If ABC = DEF, which sides and angles are congruent?
