In isosceles triangle DAC, AD is congruent to AC. Kiran knows that the base angles of an isosceles triangle are congruent. What additional
information does Kiran need to know in order to show that AB is a perpendicular bisector of segment CD?

Answers

A perpendicular bisector is a line that crosses (bisects) another line segment at 90 degrees, dividing the line segment it crosses into two equal length lines

The additional information Kiran need to know to show that AB is a perpendicular bisector is the fourth option;

DB and BC are congruent

The reason for the above selection is as follows:

The information about the isosceles triangle DAC Kiran knows are;

Triangle DAC = An isosceles triangle

Segment AD is congruent to segment AC

Segment AB is a is a line from the vertex point A to the side CD of triangle DAC

The required parameter:

The information Kiran has know so as to show that AB is a perpendicular bisector of CD

Method:

Determine an attribute present in triangle DAC with line AB drawn that is due to line AB being a perpendicular bisector

Solution:

For AB to be a perpendicular bisector, then DB and BC are congruent

Given that DB and BC are congruent, we get;

AB is congruent to AB by reflexive property

Therefore, given that AD is congruent to AC, we have;

Sides AD, AB, and DB in triangle ΔADB are congruent to the corresponding sides AC, BC, and AB in triangle ΔACB, which gives

ΔADB is congruent to ΔACB by Side-Side-Side, SSS, congruency rule

Therefore, ∠ABD ≅ ∠ABC, by Congruent Parts of Congruent Triangles are Congruent, CPCTC

∠ABD = ∠ABC by definition of congruency

∠ABD and ∠ABC are linear pair angles, therefore;

∠ABD + ∠ABC = 180°

∠ABD + ∠ABD = 2 × ∠ABD = 180° by substitution property

∠ABD = 180°/2 = 90°

∠ABD = 90° = ∠ABC, therefore, AB is perpendicular to CD and AB is a perpendicular bisector of CD

Therefore, the correct option Kiran need to know in order to show that AB is a perpendicular bisector of segment CD is the option; DB and BC are congruent
