3
If two triangles are similar, then the _____________ are proportional to the measures of corresponding sides. Remember: The perimeter is the sum of all the ______________ of a figure. Perimeters Sides Example: In the figure at the right, ABC ~ XYZ. The following proportions are true:
4
In the figure below, ABD ~ ADC. If AD = 16, AC = 31, and DC = 23, find the perimeter of ABD.
5
If two triangles are similar, then the measures of the corresponding ______________ are proportional to the measures of the corresponding sides. Remember: The _________________ is a segment that goes from a vertex and is perpendicular to the opposite “side”. Altitudes Altitude
6
If two triangles are similar, then the measures or lengths of the corresponding ___________ __________ of the triangles are proportional to the measures of the corresponding sides. Example: TSR ~ GFE. is an angle bisector of RTS. is an angle bisector of EGF. List some possible proportions: AngleBisectors
7
If two triangles are similar, then the measures of the corresponding ________ are proportional to the measures of the corresponding sides. Remember: A _______ goes from a vertex to the ________ of the opposite side. Example: CAB ~ YWX. is median of CAB. is median of YWX. List some possible proportions: Medians Median Middle
8
An angle bisector in a triangle separates the opposite side into segments that have the same ratio as the other two sides. Example: is the angle bisector of ACB. Complete the following statement:
