Each of the sails on Joshua’s sailboat forms a triangle. The side lengths of one sail are 13, 17, and 20. What is the measure of each side of the sail?*the largest angle is opposite the longest side length

• XY = 13, XZ = 20, YZ = 17

• XY = 17, XZ = 13, YZ = 20

• XY = 20, XZ = 17, YZ = 13

• XY = 13, XZ = 17, YZ = 20

Identify the triangle by its sides

• acute isosceles

• obtuse scalene

• obtuse isosceles

• acute scalene

Which angle corresponds to side VW?

• v

• U

• W

What makes this a scalene triangle?

• There is one obtuse angle

• All sides have a different length

• There are two acute angles

• There is one right angle
