When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there. So in other words no matter what way it is flipped or anything else that does not change the numbers on the sides it is congruent.
Simple, since you want to find y, in y=mx+b form, move everything to the other side.
1/2x-y=4
Move 1/2x
1/2x-y=4
-1/2x -1/2x
Making it look like,
-y=4-1/2x
Divide by the negative 1 in front of the y,
-y=4-1/2x
/-1 /-1
y=-4+1/2x
or
y=1/2x-4
Thus, this written in y=mx+b form, y=1/2x-4.
The correct answer is 226$
Answer:
D. Linear Pair Postulate
Step-by-step explanation:
In the diagram given, angle PQS and angle SQR both form a linear pair. Both angles lie on a straight line. The measure of the angle of a straight line equals 180°. So therefore, two angles of a linear pair will sum up to 180°.
According to the linear pair postulate, <PQS and <SQR are supplementary, since they form a linear pair.
Therefore, the reason for statement 2 for the two-column proof is "Linear Pair Postulate".
