How are the triangles created by the altitude related to the original triangle?

• They are different

• They are congruent

• They are similar

• They are identical

What is the formula used to find the altitude of a triangle?

• Altitude = a + b

• Altitude = a - b

• Altitude = a / b

• Altitude = √(a * b)
