Key Concepts and Definitions for Unit 7 Test
In preparing for the Unit 7 Test on Geometry, it is important to have a clear understanding of the key concepts and definitions that will be assessed. These concepts and definitions are fundamental to the study of geometry and will form the basis for solving various problems and proving geometric theorems.
Lines and Angles: One major area of focus for the test is lines and angles. It is crucial to understand the different types of angles, such as acute, obtuse, and right angles. Additionally, knowledge of complementary and supplementary angles will be necessary to solve problems involving angle measures. Understanding parallel and perpendicular lines, as well as transversals and the angles they create, is also important.
Polygons: Another important concept for the test is polygons. A polygon is a closed shape made up of straight sides. It is important to be able to identify and classify polygons, including triangles, quadrilaterals, pentagons, and hexagons. Understanding their properties, such as the sum of their interior angles and the types of lines they have, is key to solving problems involving polygons.
Congruence and Similarity: The concepts of congruence and similarity will also be assessed on the test. To determine if two figures are congruent, it is necessary to understand the criteria for congruence, such as side-side-side (SSS), side-angle-side (SAS), and angle-side-angle (ASA). Similarity, on the other hand, involves figures that have the same shape but different sizes. Understanding the concept of proportionality and the properties of similar figures will be crucial for solving similarity problems.
These are just a few of the key concepts and definitions that will be assessed on the Unit 7 Test for Geometry. It is essential to study and review these concepts thoroughly in order to be prepared for the test. Practicing with a variety of problems and working through sample proofs will also help solidify your understanding and improve your performance on the test.

Answer: The sum of the interior angles of a hexagon is equal to 720 degrees.
2. Find the measure of angle A in the triangle below:
Answer: In triangle ABC, the measure of angle A can be found using the following equation: 180 – (measure of angle B + measure of angle C).
3. How many sides does a regular octagon have?
Answer: A regular octagon has 8 sides. In a regular polygon, all sides and angles are equal.
4. Determine if the following quadrilateral is a parallelogram:
| Measurement of Side | Measurement of Diagonal | |
| AB | 4 cm | 5 cm |
| BC | 4 cm | 3 cm |
| CD | 6 cm | 6 cm |
| DA | 6 cm | 4 cm |
Answer: To determine if the quadrilateral is a parallelogram, we need to check if opposite sides are congruent and if opposite angles are congruent. In this case, AB and CD are congruent, and BC and DA are congruent, so the quadrilateral is a parallelogram.
5. Find the area of the regular pentagon below:
Answer: The area of a regular polygon can be found using the formula (perimeter * apothem) / 2. In the case of a regular pentagon, the apothem is the perpendicular distance from the center to any side.
These sample questions and answers provide a glimpse of the types of problems that may be encountered in the Geometry Unit 7 Test. It is important to study and practice problems related to angles, triangles, and polygons to ensure a good performance on the test.
