To prove: The
Explanation of Solution
Given information:
Given points Q, R, S, and T lie in the given plane m
Given two angles PQR and PQT are right angles
Formula used:
Congruency means same shape and same size
Congruent Parts of congruent
Reflexive property
If a line is perpendicular to plane than all line passing through its foot will also perpendicular to it
Perpendicular lines always form right angles
Proof:
Points Q, R, S and T lie in the plane m...........given
