Math Vocabulary 5th Grade Unit 3

A right angle is a type of angle that measures exactly 90 degrees. It is formed when two lines intersect each other and create a square corner. In a right angle, one side of the angle is vertical and the other side is horizontal, forming a perfect L shape. This measurement of 90 degrees is a defining characteristic of a right angle, making it the correct answer.

An acute angle is defined as an angle that measures between 0 degrees and 90 degrees. It is smaller than a right angle (90 degrees) and larger than a reflex angle (greater than 180 degrees).

The correct answer is "comes from the Latin word meaning 'to tax' or 'to appraise'." The word "census" is derived from the Latin word "censere," which means "to assess" or "to estimate." In ancient Rome, a census was conducted to assess the population and property of the citizens for taxation and other purposes. This meaning has carried over to the present day, where a census is still conducted to gather information about a population for various social, economic, and political reasons.

A reflex angle is an angle that measures between 180 degrees and 360 degrees. This means that it is greater than a straight angle (180 degrees) but less than a full rotation (360 degrees).

A geometry template is a tool used to measure angles and has 2 rulers - inch and centimeter scale. It is not related to the Latin word meaning "to tax" or "to appraise". It is also not specifically a flat, 2-dimensional figure made up of line segments, although it can be used to draw such figures. Additionally, it does not have 17 different figures on it.

An obtuse angle is defined as an angle that measures between 90 degrees and 180 degrees. It is larger than a right angle (90 degrees) but smaller than a straight angle (180 degrees).
