Question

Math Help Part 3 (Please Help)

Answer 1

Answer:

(a) median

(b) angle bisector

(c) altitude

Step-by-step explanation:

• The perpendicular bisector of a side of a triangle is a line perpendicular to the side and passing through its midpoint.
• The angle bisector of an angle of a triangle is a straight line that divides the angle into two congruent angles.
• A median of a triangle is a line segment drawn from a vertex to the midpoint of the opposite side of the vertex.
• An altitude of a triangle is the perpendicular segment from a vertex of a triangle to the opposite side (or the line containing the opposite side).

(a) median

IG = IH  ⇒  I is the midpoint GH, BUT it is not perpendicular to FI, so median

(b) angle bisector

m∠XYV = m∠ZYV, BUT YV is not perpendicular to XZ, so angle bisector

(c) altitude

m∠BDC = 90° but AD ≠ DC (so not perpendicular bisector)

Answer 2

I wish I could help but I suck at math
