Classify the triangle if two angles in the triangle measure 40 and 50°.

Right Triangle

Step-by-step explanation:

Let's find the missing angle:

180 - (40 + 50)

180 - 90 = 90°

So we have a right triangle!

Right Triangle

Step-by-step explanation:

If one of the angles measure 40 and the other 50 that means that the final angle is 90 which makes it a right triangle.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
