• 120⁰

• 20⁰

• 100⁰

What is the measure of angle y

• 40⁰

• 20⁰

• 80⁰

• 90⁰

3. Given the figure on the right, what side is the shortest

• LM because it is opposite the smallest angle.

• LM because it is opposite the longest angle

• LM because it is opposite the longer angle

Given the figure on the right, what angle is the largest?

• K because it is opposite, the longest side

• M because it is opposite, the shortest side

• L because it is opposite, the shortest side

Can a triangle be form using the set of lengths 20, 10, 9?

• Yes, because 20+10> 9

• No, because 10+9<20

6. The hinge theorem states that____

• If two triangles have two congruent sides, then the triangle with the larger included angle between those sides will have the longer third side

• If two triangles have two congruent sides, then the triangle with the smaller included angle between those sides will have the longer third side.

• If two triangles have two congruent sides, but the third sides have different lengths, then the two triangles are congruent

• If two triangles have no congruent sides,then the two triangles are congruent

Which of the figures and statements show the Hinge Theorem

• 
• 
• 
• 

angle 1_______angle 4

• <, since angle1 is opposite a shorter side

• >, since angle4 Is opposite a shorter side

Angle CAD _____ Angle BCA

• <,since CAD is opposite a shorter side

• >, since BCA is opposite a shorter side

Given the figure below, which angles measures greater than the measure of h

• d, e and i

• h, i and g

• a, b and c

• b, c and i
