Classify the following triangle as acute, obtuse, or right

Option B

Step-by-step explanation:

The following picture is a example of a "right triangle" or option B. Right triangles have 90 degree angles and look like a L, if you rotate the triangle to its base you would see that the 90 degree angle looks like a L making it a right triangle. It's not option A because acute angles have to be smaller then 90 degrees in order for it to be acute, it's not obtuse because the angle has to be greater then 90 degrees in order to be a obtuse triangle.

Hope this helps.

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

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
