Question

When constructing perpendicular lines with a compass and straightedge, how should you start the construction?
A.Open the compass and mark two points of intersection between arcs from the given line.
B. Use a straightedge to find the length of the given line and then make an arc above it.
C. Open the compass to the width of the original line to measure it.
D. Use a straightedge to create two arcs above and below the original line.

Answer 1

Answer 2

well i think it's B check me if i'm right

Answer 3

@ganeshie8 what do you think

Answer 4

We cannot measure anything with straight edge in constructions, so B isn't right

Answer 5

For the same reason, C is also incorrect

Answer 6

yes i agree with @ganeshie8

Answer 7

D is wrong because, straight edge is not used for drawing arcs

Answer 8

and leaves a as the answer thank you @ganeshie8

Answer 9

all medal @ganeshie8 he is the best math or any subject helper

Answer 10

last question!
When constructing inscribed polygons and parallel lines, how are the steps similar?
A protractor and ruler are used to take accurate measurements.
A compass is used to draw arcs.
Four right angles are created.
There are no similarities.

Answer 11

protractor and ruler are NOT allowed in constructions, so A is wrong

Answer 12

B could be correct, but look at other options also

Answer 13

What are the polygons being inscribed into? A circle?
Are the polygons regular?

I would say the answer is c because a compass is used in almost all constructions

Answer 14

that is what i think i am not giving direct answers

Answer 15

@alekos

Answer 16

I'd go with
A compass is used to draw arcs.

Answer 17

so then b

Answer 18

i was right i feel so happy

Answer 19

maybe

Answer 20

GOT 100% IT WAS RIGHT! TANKS ALL
