- a Does the similarity relationship have a reflexive property for triangles and polygons in general? b Is there a symmetric property for the similarity of triangles and polygons? c Is there a transitive property for the similarity of triangles and polygons?arrow_forwardProve that the altitude drawn to the hypotenuse of a right triangle separates the right triangle into two right triangles that are similar to each other and to the original right triangle.arrow_forwardWhat type of trapezoid a has congruent diagonals. b has congruent base angles.arrow_forward
- Prove: In a circle containing two unequal chords, the longer chord corresponds to the larger central angle. HINT: You may use any theorems stated in this section.arrow_forwardConsider any regular polygon; find and join in order the midpoints of the sides. What does intuition tell you about the resulting polygon?arrow_forwarda Argue that the midpoint of the hypotenuse of a right triangle is equidistant from the three vertices of the triangle. Use the fact that the congruent diagonals of a rectangle bisect each other. Be sure to provide a drawing. bUse the relationship from part a to find CM, the length of the median to the hypotenuse of right ABC, in which mC=90, AC = 6, and BC = 8.arrow_forward
- The Segment-Addition Postulate can be generalized as follows: The length of a line segment equals the sum of the length of its parts. State a general conclusion regarding AE based on the following figure.arrow_forwardHA hypotenuse-angle is also a valid method for proving that two right triangles are congruent a Given that AD and ABDE in the right triangles shown, can HA be used to verify that ABCDEF? b Name another method SSS, SAS. etc. that can be used to verify that these triangles are congruent.arrow_forwardThe bisectors of two consecutive angles of HJKL are shown. What can you conclude regarding P?arrow_forward
- a Are any two regular pentagons similar? b Are any two equiangular pentagons similar?arrow_forwardDraw a triangle with three acute angles. Construct angle bisectors for each of the three angles. On the basis of the appearance of your construction, what seems to be true?arrow_forwardDraw an obtuse triangle and construct the three perpendicular bisectors of its sides. Do the perpendicular bisectors of the three sides appear to meet at a common point?arrow_forward
