2. TRUE/FALSE 1) If the ratio of the sides of two hexagons is, then the ratio of the perimeters is, then the ratio of the perimeters is 2) A sector of a circle is bounded by an arc and two radii. 3) The area of a segment of a circle is the area of the sector minus the area of the triangle.

3. True/False 4) If two figures are similar and the ratio of their perimeters is, then the ratio of their sides is 5) If two triangles are similar and the ratio of their sides is 1:2, then the ratio of their heights is also 1:2. 6) The area of a regular polygon can be found by multiplying the apothem by the perimeter.

4. Answers to True / False 1) False. You need to know if the hexagons are similar or if they are both regular. 2) True 3) True 4) False. If two figures are similar and the ratio of their perimeters is P 1 :P 2, then the ratio of their sides is s 1 :s 2. 5) True 6) False. The formula is A= ½ aP
