Answer:
27. Alternate exterior angles are congruent.
28. Same-side interior angles are supplementary.
Step-by-step explanation:
27. The two angles whose measures are set equal by the equation are on opposite sides of the transversal, so are "opposite." They are "outside" the space between the parallel lines, so are "exterior." These descriptors identify the angles as "opposite exterior" angles. The theorem/postulate that lets you set their measures equal is ... [the one written above].
28. The two angles whose measures are added in the equation are on the same side of the transversal, so are "same-side" angles. They are "inside" the space between the parallel lines, so are "interior." These descriptors identify the angles as "same-side interior" angles. The theorem/postulate that says their measures sum to 180° is ... [the one written above].
Answer:
- 1. Adjacent, 2. Vertical, 3. Neither
Step-by-step explanation:
1.
- The first pair is adjacent as they have common side.
2.
- The second pair is vertical as opposite angles of the crossed lines.
3.
- The third pair has no relationship with each other, so neither is the answer.
Answer:
The coordinates of D' are (1,-1)
Step-by-step explanation:
The point D in the figure has co-ordinates (2,-2) as shown in the figure.
The figure is dilated by a factor of 1/2
So, multiply the coordinates of D (2,-2) by 1/2
D' = (1/2*2, 1/2*-2)
D' = (1,-1)
So, the coordinates of D' are (1,-1)
The way you convert is by dividing your answer to the question by 1,2or how many they are talking about . Once you do that you will get your answer which may be a decimal and the you put the unit kg for kilograms. so that will be the answer to the problem.
