... right angles) and angle PSR is congruent to angle QSR (right angles are congruent) Since segments RS and RS are congruent through reflexive property, then triangle PSR is congruent to triangle QSR (ASA). Therefore, segments PR and QR are congruent (CPCTC). But this is impossible because it contradic ...

... Recall that an angle bisector is a ray that divides the angle into two congruent parts. We will use the magic of a compass and straightedge to create one of these divisive rays and then use congruent triangles ...

... The flagpole, wire, and ground form a right triangle with the wire as the hypotenuse. Because you know an angle and the measures of its adjacent side and the hypotenuse, you can use the cosine ratio to find the height of the flagpole. height cos 35° = 20 ...

HW #18
... Answer: rectangles (by definition), squares (by inheritance) (b) The opposite sides are always parallel to each other. Answer: parallelograms (almost by definition), then rectangles, rhombuses, and squares (all by inheritance) (c) The interior angle total is 360o . Answer: any convex quadrilateral, ...
