Lm  has the endpoints l at –5 and m at 9. to find the point  x  so that  x  divides the directed line segment  lm  in a 2: 3 ratio, use the formula  x  =  (x2  –  x1) +  x1.x  =  (9  – (–5)) + (–5)

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.

Vertical angles must check all that apply
