wat do you need with

OpenStudy (anonymous):

imean what do you need help with

OpenStudy (anonymous):

i need to be explained how they got that

OpenStudy (anonymous):

This should explain it if not let me know ..... Proof of Theorem: If ONE PAIR of opposite sides of a quadrilateral are BOTH parallel and congruent, the quadrilateral is a parallelogram. (Remember: when attempting to prove a theorem to be true, you cannot use the theorem as a reason in your proof.) STATEMENTS REASONS 1 1 Given 2 Draw segment from A to C 2 Two points determine exactly one line. 3 3 If two parallel lines are cut by a transversal, the alternate interior angles are congruent. 4 4 Reflexive property: A quantity is congruent to itself. 5 5 SAS: If two sides and the included angle of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent. 6 6 CPCTC: Corresponding parts of congruent triangles are congruent. 7 7 If two lines are cut by a transversal and the alternate interior angles are congruent, the lines are parallel. 8 8 A parallelogram is a quadrilateral with both pairs of opposite sides parallel.

heres another

Okayee now with this you have to look at the The angles in matching corners are called Corresponding Angles.Corresponding sides and angles are a pair of matching angles or sides that are in the same spot in two different shapes. Look at the pictures below to see what corresponding sides and angles look like. Note: These shapes must either be similar or congruent.

????????????

OpenStudy (anonymous):

that answer is correct because of congruent sides on the angles as i showed you up above

OpenStudy (anonymous):

ok?

OpenStudy (anonymous):

ok.....do you get ihtt

OpenStudy (anonymous):

alittle

OpenStudy (anonymous):

kayee so where are you confused at nww
