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

∠1 and ∠2 both are right angles.

Step-by-step 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.

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
