Use the drop-down menus to complete the paragraph proof. we are given that xy is parallel to zw. if xz is a transversal that int
ercepts xy and zw, angle and angle are alternate interior angles. since xy is parallel to zw, we know that these angles are . we also know that angle xvy and angle zvw are angles, and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.
A^2 + b^2 = c^2...a and b are the legs and c is the hypotenuse 20^2 + 21^2 = c^2 400 + 441 = c^2 841 = c^2 sqrt 841 = c 29 = c <== third straw will be 29 cm
