Question

Look at triangle KLM. Segment KO is 8 inches.

Which option could be the correct dimensions of the segments in the triangle?

KO = 8 inches, OQ = 6 inches
KO = 6 inches, OQ = 2 inches
KO = 6 inches, KQ = 12 inches
KO = 8 inches, KQ = 12 inches

Answer 1

I think its the last one KO = 8 and KQ = 12

Answer 2

Look at triangle PQR.
Which other segment is certain to pass through O?

the perpendicular bisector of side RQ
the segment that connects point R to the midpoint of side PQ
the segment that divides angle PRQ into two congruent angles
the segment from point O to side PR that meets PR at a right angle

Answer 3

first question is correct , KQ = 12, coz of 2 : 1 ratio of median

Answer 4

yay :)

Answer 5

I also have one more after this one btw

Answer 6

I think the second one is B, but im not quite sure...

Answer 7

in the second pix, it shows "small ticks" - they mean those are congruent angles,

it is showing angle - bisectors

Answer 8

Describe the process to construct an acute scalene triangle with vertices PQR using only a compass and straightedge, where Q is a point on a horizontal line segment XY.

My answer:

Step 1: you put your compass at point Q and mark a radius (doesn't matter what, can be random) and make an arc on the line XY.

Step 2: Keep the compass at the same place, but change the radius and mark another arc, however, you do not make a mark on the line XY, but anywhere on the plane.

Step 3: Place your compass on the point where the arc meets line XY and change the radius once again and make an arc to meet the second arc.

Step 4: Use the straightedge to join all the three points.

Done!

how does this sound?

Answer 9

I also thought it might be D?

Answer 10

for the second one

Answer 11

no no, i meant B not D, sorry

Answer 12

for the second one, its the angle bisectors meeting point, so the answer is this :

the segment that divides angle PRQ into two congruent angles

Answer 13

really, wow... that's the on I thought was wrong.... lol

Answer 14

thanks

Answer 15

how does the essay one look?

Answer 16

there's also this one:
A triangle can be classified by its angles and by its sides.

Part 1: Use these two ways of classification to describe a right isosceles triangle.

Part 2: Name a triangle with only a different angle classification as a right isosceles. Identify one similarity and one difference between this new triangle and the right isosceles triangle.


My answer:

Part 1: A right isosceles triangle is called just that because it has one right angle that measures 90˚ and two sides that are congruent.

Part 2: An acute isosceles triangle is one different angle classification. The largest angle in this triangle can measure is 75˚, but it still has two sides that are congruent.

Answer 17

sorry if it too much at once...

Answer 18

its*

Answer 19

the essay one doesnt sound good

Answer 20

it doesnt say how its acute or scalene

Answer 21

no? aww man... Im really bad at explaining how to construct triangles, I always get them wrong :(

Answer 22

could u explain it to me, possibly??

Answer 23

1 sec

Answer 24

k

Answer 25

to construct a Acute-Scalene triangle, we combine the steps of
1) Acute triangle ( all angles < 90)
2) Scalene triangle ( all sides different)

Answer 26

lets see how to construct this

Answer 27

okay

Answer 28

Describe the process to construct an acute scalene triangle with vertices PQR using only a compass and straightedge, where Q is a point on a horizontal line segment XY.

Answer 29

since Q is given as the point on the horizontal line segment XY,

step 1 : Place the compass on the point Q , and swing an arc from one side of the line to the other side. This will create a semi-circle.
