1. This geometric object has no dimension and is represented as a single dot in space

Answer: C) point

✔ Explanation:
A point is a location in space with no size, length, width, or height — it has no dimensions. It is represented by a dot.
- A line has one dimension (length).
- A ray is part of a line with one endpoint and extends infinitely in one direction.
- A plane is two-dimensional (length and width).

So, the correct answer is C) point.

2. These two lines will never intersect

Answer: C) Parallel Lines

✔ Explanation:
Parallel lines are lines in the same plane that never meet, no matter how far they are extended. They maintain a constant distance apart.
- Bisector: A line or ray that divides something into two equal parts — not relevant here.
- Perpendicular lines intersect at 90° angles — so they *do* intersect.
- "Not possible" is incorrect because parallel lines *are* possible and do not intersect.

So, the correct answer is C) Parallel Lines.

3. This is a...
*(Image shows triangle ABC with all three sides marked with the same tick marks)*

Answer: C) an equilateral triangle

✔ Explanation:
The tick marks on the sides indicate equal lengths. Since all three sides have the same tick mark, this means all sides are equal.
- An equilateral triangle has three equal sides and three equal angles (each 60°).
- A scalene triangle has no equal sides.
- An obtuse triangle has one angle greater than 90°.
- A right triangle has one 90° angle.

So, the correct answer is C) an equilateral triangle.

4. Formed by two rays that share a common end point

Answer: B) Angle

✔ Explanation:
An angle is formed when two rays originate from the same point (called the vertex).
- Congruent means equal in measure — not a shape or figure.
- Opposite rays are two rays that form a straight line (180°).
- A line is a straight path extending infinitely in both directions.

So, the correct answer is B) Angle.

5. Two angles that add to be 90 degrees

Answer: B) Complementary

✔ Explanation:
Two angles are complementary if their sum is 90 degrees.
- Supplementary angles add up to 180 degrees.
- Right angle is a single angle measuring 90°.
- Angles is too general.

So, the correct answer is B) Complementary.

6. The Pythagorean Theorem only works on what type of triangle?

Answer: B) Right

✔ Explanation:
The Pythagorean Theorem states:
> $ a^2 + b^2 = c^2 $
where $ c $ is the hypotenuse (longest side), and $ a $ and $ b $ are the legs of a right triangle.

This theorem only applies to right triangles, where one angle is exactly 90°.
- Isosceles triangles have two equal sides, but not necessarily a right angle.
- So, while some isosceles triangles can be right, the theorem isn't limited to isosceles — it's specifically for right triangles.

So, the correct answer is B) Right.
