Question

Hey can somone help me with some questions

Answer 1

yeah

Answer 2

ok one sec let me post

Answer 3

In ΔABC shown below, Line segment AB is congruent to Line segment BC:
Triangle ABC, where sides AB and CB are congruent

Given: line segment AB≅line segment BC

Prove: The base angles of an isosceles triangle are congruent.

The two-column proof with missing statement proves the base angles of an isosceles triangle are congruent:


Statement Reason
1. segment BD is an angle bisector of ∠ABC. 1. by Construction
2. ∠ABD ≅ ∠CBD 2. Definition of an Angle Bisector
3. 3. Reflexive Property
4. ΔABD ≅ ΔCBD 4. Side-Angle-Side (SAS) Postulate
5. ∠BAC ≅ ∠BCA 5. CPCTC


Which statement can be used to fill in the numbered blank space?

Answer 4

well...depends n the questions really... :P

Answer 5

which one is you7r numbered blank space/

Answer 6

i wanna think its three but it could be four

Answer 7

@triciaal

Answer 8

its just asking for the reflective property

Answer 9

Line segment BD≅ Line segment AC
Line segment BD≅ Line segment BD
Line segment AC≅ Line segment AC
Line segment AD≅ Line segment DC

Answer 10

these are the choices

Answer 11

im pretty sure it is c

Answer 12

yep
i agree

Answer 13

ok can i ask one more

Answer 14

totally!

Answer 16

wait one sec

Answer 17

Use ΔABC to answer the question that follows:

Triangle ABC. Point F lies on AB. Point D lies on BC. Point E lies on AC. AD, BE, and CF passes through point G. Line AD passes through point H lying outside of triangle ABC. Line segments BH and CH are dashed

Given: ΔABC

Prove: The three medians of ΔABC intersect at a common point.

When written in the correct order, the two-column proof below describes the statements and justifications for proving the three medians of a triangle all intersect in one point:


Statements Justifications
Point F is a midpoint of Line segment AB Point E is a midpoint of Line segment AC Draw Line segment BE Draw Line segment FC by Construction
Point G is the point of intersection between Line segment BE and Line segment FC Intersecting Lines Postulate
Draw Line segment AG by Construction
Point D is the point of intersection between Line segment AG and Line segment BC Intersecting Lines Postulate
Point H lies on Line segment AG such that Line segment AG ≅ Line segment GH by Construction
I BGCH is a parallelogram Properties of a Parallelogram (opposite sides are parallel)
II Line segment BD ≅ Line segment DC Properties of a Parallelogram (diagonals bisect each other)
III Line segment GC is parallel to line segment BH and Line segment BG is parallel to line segment HC Substitution
IV Line segment FG is parallel to line segment BH and Line segment GE is parallel to line segment HC Midsegment Theorem
Line segment AD is a median Definition of a Median
Which is the most logical order of statements and justifications I, II, III, and IV to complete the proof?

Answer 36

In ΔABC shown below, ∠BAC is congruent to ∠BCA:
Triangle ABC, where angles A and C are congruent

Given: Base ∠BAC and ∠ACB are congruent.

Prove: ΔABC is an isosceles triangle.

When completed (fill in the blanks), the following paragraph proves that Line segment AB is congruent to Line segment BC making ΔABC an isosceles triangle.

Construct a perpendicular bisector from point B to Line segment AC.
Label the point of intersection between this perpendicular bisector and Line segment AC as point D:
m∠BDA and m∠BDC is 90° by the definition of a perpendicular bisector.
∠BDA is congruent to ∠BDC by the definition of congruent angles.
Line segment AD is congruent to Line segment DC by _______1________.
ΔBAD is congruent to ΔBCD by the _______2________.
Line segment AB is congruent to Line segment BC because corresponding parts of congruent triangles are congruent (CPCTC).
Consequently, ΔABC is isosceles by definition of an isosceles triangle.
