(geometry a) review of reasoning and proof quiz

1.) what is the inverse of the following statement? if it is raining, then i will carry an umbrella.

2.) write the following reversible statement as a biconditional: if two perpendicular lines intersect, they form four 90° angles.

3.) which reason justifies the statement m< dab that is 100°?

4.) use the vertical angles theorem to name a pair of congruent angles in the image shown.

Drag the tiles to the boxes to form correct pairs. not all tiles will be used. match each set of vertices with the type of quadrilateral they form

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
