Question 6: what is the least common denominator (lcd)?

question 7: a common denominator is when the denominators of two or more fractions are the same.

true
false

question 8: what is a fraction in which the numerator is greater than the denominator?

question 9: what is a reciprocal?

question 10: what is a proportion?

(last question) question 11: what is a variable?

this answer is !

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
