 # Free Printable angles anchor chart for classroom[PDF]

Last Updated on July 15, 2020 by Editorial Team

Angles and its types are the initial topics taught right in the beginning of the geometry series. Students are required to put their strong visual, descriptive, drawing, logical and applied skills forward while learning about it. Building strong fundamentals early in the topic is necessary to form base for advanced geometry problems about to come in senior years.

In geometry, an angle is the figure formed at the intersection of two intersecting lines. The angle is measured in degrees. In general sense, it measures the rotation required to superimpose one of two intersecting lines on the other.

One important thing that we always advocate is to give repetitive experience of the fundamental concepts of a topic right in the beginning. Similar practice is required for angles and geometry. As when the topic is initially introduced to the students, the impression is stronger if the topic is discussed in a routine with special strategy for those struggling severely.

Charts do the same thing to an extent. Charts and diagrams in the classroom enable students to see concepts visually laid out in an organized way. Students process the charts content pretty well and easily make connections with the topic.

In this post, we present you the anchor charts of angles for the classroom. We covered angles, its types & classification, and relationships through this chart. Kids learning geometry can downlod the free printable of these angles anchor charts and its pdf version below. A little quiz in the beginning of the class in a scheduled routine is a suitable approach to get the most out of this.

First and foremost important thing to learn is the classification of angles. Angles are primarily divided into following types:

1. Acute Angle : In this type, angle formed by two intersecting lines measures less than 90 degrees.
2. Right Angle : In this type, angle formed by two intersecting lines measures exactly 90 degrees.
3. Obtuse Angle : In this type, angle formed by two intersecting lines measures greater than 90 degrees.
4. Straight Angle : In this type, angle formed by two intersecting lines measures exactly 180 degrees.
5. Reflex Angle : In this type, angle formed by two intersecting lines measures greater than 180 but less than 360 degrees.

Angles are further classified according to the type of relationships formed. The angles is divided into :

1. Supplementary Angles : When the sum of two adjacent angles add upto 180 degrees, it is called supplementary angles.
2. Complementary Angles : When the sum of two adjacent angles add upto 90 degrees, it is called complementary angles.
3. Adjacent Angles : Two angles next to each other are called adjacent angles
4. Vertical Angles : Two non adjacent, congruent angles formed across each other by two intersecting lines are called vertical angles.
