Question

If $\Delta PQR$ is a obtuse triangle with $\angle Q$ as the obtuse angle, then the measure of $\angle Q>{90}^o$ and measure of $\angle P$ and measure of $\angle R$ is:

• A. $<{90}^o$
• B. $>{90}^o$
• C. $>{180}^o$
• D. $<{180}^o$

Answer 1

Answer: (A)

$<{90}^o$

If $\Delta PQR$ is a obtuse triangle with $\angle Q$ as the obtuse angle, then the measure of $\angle Q>{90}^o$ and measure of $\angle P$ and measure of $\angle R$ is $<{90}^o.$

This can be verified using angle sum property.
