Question

Anya is constructing a circle inscribed in a triangle ABC. In the first step she constructs the angle bisectors of angle B and angle C and labels the point of intersection of the bisectors as Q. Which could be the next reasonable step?

She will construct a line passing through point Q and vertex A.

She will construct a line through vertex A perpendicular to segment BC.

She will construct a perpendicular bisector of segment BC.

She will construct a line through point Q perpendicular to segment AB.

Answer 1

It's D

Answer 2

Why do you say it's D?

Answer 3

Do you have a particular reason for picking D?

Answer 4

I was looking at how to construct an inscribed circle and it said after finding the angle bisectors to create a perpendicular line through the incenter

Answer 5

Let me check...hold on...

Answer 6

Alright. If you skip the optional step, then it's D.

Answer 7

Do you think you can help on this one?
The figure below shows AB = 4 units and BD = 6 units.



If the area of triangle ADE is 50 square units, what is the area of the trapezoid BCED?

40 square units

44 square units

48 square units

42 square units

Answer 9

Do you have any idea on this one?

Answer 10

Nope

Answer 11

I think the base and height of the triangle are both 10 though

Answer 12

Alright. Are you familiar with how ratios work for similar figures involving side lengths and area?

Answer 13

I guess not :/

Answer 14

Yea...sorry I was looking at my test and not paying attention to this
