The vertices of a triangle are a(–2, 2), b(9, 0), and c(1, –4). if the triangle is a right triangle, which vertex is the right angle? a. a b. b c. c d. none, it is not a right triangle

Write an equation in point-slope form for the line through the given point that has the given slope (-2,-7); m=-3/2

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.

Me with geometry ! in this figure, bc is a perpendicular bisects of kj. dm is the angle bisects of bdj. what is the measure of bdm? •60° •90° •30° •45°
