Lines shapes test answers: worked solutions

Question 1 – Name the figure [2 pts]

It starts at A, has one endpoint, and goes through B: ray AB
It has two endpoints: segment CD

Scoring: 1 point for each correct name. Accept “line segment CD” and “ray AB”.

Question 2 – Draw lines [2 pts]

Two examples are shown.

Parallel and perpendicular lines.

Scoring: part a, 1 point for two lines that never meet and stay the same distance apart. Part b, 1 point for two lines crossing at 90° with the right angle marked or clearly square.

Question 3 – Name the angles [2 pts]

Angle P is smaller than a square corner: acute
Angle Q is wider than a square corner but not a straight line: obtuse

Scoring: 1 point for each correct classification.

Question 4 – Classify triangles [2 pts]

It has a 90° angle: right triangle
130° is more than 90°: obtuse triangle

Scoring: 1 point for each correct classification.

Question 5 – Study a quadrilateral [3 pts]

2 pairs (both pairs of opposite sides have arrows)
0 right angles (no little squares)
Parallelogram

Scoring: 1 point for each correct part.

Question 6 – Sort the shapes [3 pts]

Rectangle: (a) 2, (b) 4. Trapezoid: (c) 1, (d) 0. Right triangle: (e) 0, (f) 1.

(a) 2 (b) 4 (c) 1 (d) 0 (e) 0 (f) 1

Scoring: 1 point for each row if both answers are correct.

Question 7 – Read the map [3 pts]

Main St and Oak St
1st Ave and Main St (or 1st Ave and Oak St)
60° is less than 90°: acute

City map.

Scoring: 1 point for each correct part.

Question 8 – Always, sometimes, never [3 pts]

always: every rectangle has 4 right angles.
never: two right angles leave no room to close a triangle.
sometimes: a rectangle does, but a kite-shaped quadrilateral does not.

Scoring: 1 point for each correct word.
