Question

difference between corresponding and alternate angles

Answer 1

One of corresponding angles is alwaysinterior (in between parallel lines) and another - exterior (outside of the area in between parallel lines). Two acuteangles a and c' , formed by different parallel lines when intersected by a transversal, lying on the opposite sides from a transversal, are calledalternate..

Answer 2

When two triangles are congurte so the triangle are same as in the side and angle since let triangles ABC and PQR
so since angle B=angle Q
And in alternate when any lines are parallel and cutted with a line which called transversal
