Since Sawyer is writing a proof for his construction of an angle bisector, a statement that is missing from his plan is: b) HA = HB and AL = BL.
In Mathematics and Euclidean Geometry, an angle bisector is a type of line, ray, or segment, that typically divides or bisects a line segment exactly into two (2) equal and congruent angles.
Based on the definition of angle bisector, we can logically deduce the following angle measures;
Statement Reasons
HA = HB and AL = BL Radii of constructed arc are same length.
LH = LH Reflexive property
ΔHBL ≅ ΔHAL SSS Congruence property
m∠AHL ≅ m∠BHL Corresponding angles of congruent triangles.
In conclusioon, HA = HB and AL = BL because the radii of constructed arc have the same length, and point L is equidistant to A and M.
