First two need to be answered and last two need to be checked. (If you don’t see the attachments wait..)

Answer:

  1. ∠PQR measures 40°
  2. x = 7
  3. They form concentric circles
  4. Yes, according to the triangle inequality

Step-by-step explanation:

1. ∠PQR is an alternate interior angle with the one marked 40°, so it has the measure 40°.

∠PRQ is an alternate interior angle with the one marked 60°, so it has the measure 60°.

Among the answer choices, the one describing ∠PQR as 40° is the only correct one.

__

2. ∠BAD = 2×∠BAE

  130 = 2(9x + 2) . . . substitute the given expressions

  65 = 9x + 2 . . . . . divide by 2

  63 = 9x . . . . . . . . .subtract 2

  7 = x . . . . . . . . . . . .divide by 9

__

3. Think again. Anything being rotated follows a <em>circular path</em>. Circular paths with different radii and the same center are concentric circles.

Straight lines connecting the pre-image and image points will be parallel (and different lengths), but the question is concerned with <em>paths</em>, not <em>endpoints</em>.

Why the path is described as "concentric circles," we're not sure. The path for a 90° rotation will be a 90° arc. It is perfectly reasonable to describe the paths of the two points as <em>concentric arcs</em>, rather than <em>concentric circles</em>. See the attachment.

__

4. Correct. The triangle inequality requires the sum of the two shortest side lengths exceed the longest side length. Here, that means 2+5 > 5 (true). The "toothpicks" meet the requirements of the triangle inequality, so will make a triangle.

The "triangle sum theorem" has to do with angles, not side lengths.
