1. None of the three planes intersect 2. The three planes intersect in one line 3.The three planes intersect in one point 4. Two planes do not intersect, The third plane intersects the other two. 5. Exactly two planes intersect, The third plane does not intersect the other two Tell whether each of the following situations involving three planes is possible or not possible

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

step-by-step explanation:

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.
