Answer:

  • AE is the median of △ABC

  • AD is the altitude of △ABC

In △ABC: D and E are points on BC such that BE=CE, and AD ⊥ BC. What can you conclude?

If the base of a triangle is equal to the altitude, what would be true for the area? (let x be equal to the base)

The area would be 1/2(x)^2, because x is always being multiplied by itself

New cards
6

At what point could you use CPCTC in a proof?

Only after you have proved at least 2 triangles congruent in the steps before that

New cards
7

What kind of angle is formed with an altitude?

90° or a Right Angle
