Question 62

Using the given information, name the right angles in each part of the given figure.

a) $BA\perp BD$

b) $RT\perp ST$

c) $AC\perp BD$

d) $RT\perp SW$

e) $AC\perp BD$

f) $AE\perp CE$

g) $AC\perp CD$

h) $OP\perp AB$

Answer 1

A right angle is an angle of measure ${90}^{\circ }$. It is formed by two perpendicular lines.

a) $\angle ABD$ because $BA\perp BD$.

b) $\angle RTS$ because $RT\perp ST$.

c) $\angle ACD$ and $\angle ACB$ because $AC\perp BD$.

d) $\angle RTW$ and $\angle RTS$ because $RT\perp SW$.

e) $\angle AED,\angle AEB,\angle BEC$ and $\angle DEC$ because $AC\perp BD$ and E is their point of intersection.

f) $\angle AEC$ because $AE\perp CE$.

g) $\angle ACD$ because $AC\perp CD$.

h) $\angle AKO,\angle AKP,\angle BKO$ and $\angle BKP$ because $OP\perp AB$ and K is their point of intersection.
