5. when the same side is part of two different triangles, you can use the property to say that that side is congruent to itself.

6. use a compass and straightedge to construct a line perpendicular to the given line through point p.
remember to leave all of your construction marks. see lesson 3.02. (pic below)

Use the following statements to write a compound statement for the conjunction or disjunction. then find its truth value. p: an isosceles triangle has two congruent sides. q: a right angle measures 90° r: four points are always coplanar. s: a decagon has 12 sides. a) a right angle measures 90° or an isosceles triangle has two congruent sides; true. b) a right angle measures 90° and an isosceles triangle has two congruent sides; true. c) a right angle measures 90° and an isosceles triangle does not have two congruent sides; false. d) a right angle measures 90° or an isosceles triangle does not have two congruent sides; true.
