Incorrect. $\displaystyle\angle{M}{O}{N}\usepackage{cmbright}\Huge\$ measures $\displaystyle{{90}}^{\circ}\usepackage{cmbright}\Huge\$ , as it is a right angle. Since $\displaystyle\angle{M}{O}{Q}\usepackage{cmbright}\Huge\$ is a straight angle, $\displaystyle\angle{N}{O}{Q}\usepackage{cmbright}\Huge\$ also measures

$\displaystyle{{90}}^{\circ}\usepackage{cmbright}\Huge\$ . So the measures of $\displaystyle\angle{N}{O}{P}\usepackage{cmbright}\Huge\$ and $\displaystyle\angle{P}{O}{Q}\usepackage{cmbright}\Huge\$ must total $\displaystyle{{90}}^{\circ}\usepackage{cmbright}\Huge\$ .
