Question

If line t is perpendicular to both line l and line m, then ∠1 and ∠2 are both ____ angles. Question acute right obtuse complementary

Answer 1

They are both right angles. 

Answer 2

∠1 and ∠2 both are right angles.

Explanation:

Given that if line t is perpendicular to both line l and line m, then

we have to find about the angle ∠1 and ∠2

As given line l is perpendicular to both line l and line m,

Therefore the point at which the ;line intersect the two lines l and m at 90° i.e

∠1 and ∠2 both angles are formed at the intersection points of line t with l and m.

Hence, ∠1 and ∠2 both are right angles.
