What additional information is needed to prove the triangles are congruent by the SAS Postulate? a. AC ≅ BD
b. AC ⊥ BD
c. ∠CBA ≅ ∠CDA
d. ∠BAC ≅ ∠DAC

Which is the solution to the inequality? 2 3/52 1/15 b< 3 2/15 b> 3 2/15

Write as a product: ac^2–ad+c^3–cd–bc^2+bd

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle? by using compass take the measures of angle and draw the same arc according to it.
