Given: ∠PQR and ∠RQS are supplementary angles and m∠PQR=115° Prove: ​∠RQS​ is an acute angle. The figure shows vertical line P S. Point Q is on the line with point R to the right of the line. Ray Q R is drawn. Angle P Q R appears to be an obtuse angle.

A3-dimensional figure has a square base and 4 lateral faces that meet at a point. explain the difference between the cross sections when a slice is made perpendicular to the base through the vertex, and when a slice is made perpendicular to the base and not through the vertex
