- In a particular type of regular polygon, the length of the apothem is exactly one-half the length of a side. What type of regular polygon is it?arrow_forwardUse Exercise 33 and the following drawing to complete the proof of this theorem: The length of the median of a trapezoid is one-half the sum of the lengths of the two bases. Given: Trapezoid ABCD with median MN Prove: MN=12(AB+CD) 33. Use Theorem 5.6.1 and the drawing to complete the proof of this theorem: If a line is parallel to one side of a triangle and passes through the midpoint of a second side, then it will pass through the midpoint of the third side. Given: RST with M the midpoint of RS;MNST Prove: N is the midpoint of RTarrow_forwarda Are any two regular pentagons similar? b Are any two equiangular pentagons similar?arrow_forward
- Consider the triangular prism shown in Exercise 2. a How many vertices does it have? b How many edges lateral edges plus base edges does it have? c How many faces lateral face plus bases does it have?arrow_forwardIn Exercises 17 to 30, use the formula A=12aP to find the area of the regular polygon described. Find the area of a regular pentagon with an apothem of length a = 6.5 in. and each side of length s = 9.4 in.arrow_forwardIn Exercises 39 and 42, refer to the line segments shown. Use the following theorem to construct a triangle similar to the given triangle but with sides that are twice the length of those of the given triangle. Theorem: If the lengths of the three pairs of sides for two triangles are in proportion, then those triangles are similar SSS.arrow_forward
- A satellite dish in the shape of a regular dodecagon 12 sides is nearly circular. Find: a mAB b mABC c mABC inscribed anglearrow_forwardIn Exercises 17 to 30, use the formula A=12aP to find the area of the regular polygon described. Find the area of a regular pentagon with an apothem of length a = 5.2 cm and each side of length s = 7.5 cm.arrow_forward
