In geometry, we use 'tic' marks to indicate congruent measures and a couple of ways to indicate congruent angles. One is to put an arc in the angle with a tic mark. The other is to use one arc to indicate a measure and two or three arcs to identify congruent angles.

Below are eight of the geometric figures we have discussed in class. Identify them as specifically as possible and justify your answer with reference to side length and/or angle measure.

 

**MH 183 Images of Geometric Shapes:**

1. **Triangle**: A scalene triangle is depicted with vertices marked by red dots. The sides are all of different lengths, indicated by different line markings.

2. **Square**: A square with equal-length sides is shown. Each corner is marked with a red dot, and right angles are indicated by small black squares.

3. **Rectangle**: A rectangle with opposite sides of equal length is illustrated. Right angles are indicated at the corners.

4. **Equilateral Triangle**: All sides are equal, represented by identical line markings. An interior angle is marked to indicate it is also equivalent to the other angles.

5. **Parallelogram**: A four-sided shape with opposite sides parallel and equal. Angles within the shape are marked to show opposite angles are equal.

6. **Isosceles Triangle**: Two sides of equal length are marked with identical line markings. The base angles are equal, as indicated by arcs.

7. **Rhombus**: A quadrilateral with all sides of equal length is shown. Opposite angles are equal, and this is visually indicated by arcs inside.
