Angle and Triangle Flash CardsYou need 15 index cards for this!
Angle A B C
Two rays with a common endpoint called a vertexTwo rays with a common endpoint called a vertex. Always name an angle with the vertex in the middle.
Angles that share a vertex and a side.
Congruent Angles 64° 64° X Y
Angles with the same measure.
Angles formed by intersecting lines and are opposite each otherAngles formed by intersecting lines and are opposite each other. Vertical angles are always congruent!
The measure of the angle is less than 90°.
The measure of the angle is greater than 90° and less than 180°.
The measure of the angle is 90°.
The sum of the two angles is 90°.
The sum of the two angles is 180°.
All three sides have different lengths:
Has at least 2 congruent sides
All three sides are congruent
All of the angles are acute(less than 90°)
One obtuse angle (greater than 90 less than 180)
Has one right angle (90°)

Angles and Triangles.
Lines, Segments, and Rays. Line A line is perfectly straight and extends forever in both directions. Any two points on the line can be used to name.
Basic Definitions in Geometry
Bell Work Name the Angle in four different ways
Classifying Triangles Students will classify triangles using the lengths of the sides and the angles. S. Calahan October 2010.
Triangles 1 The Basics. 2 Naming Triangles For example, we can call the following triangle: Triangles are named by using its vertices. ∆ABC∆BAC ∆CAB∆CBA∆BCA.
Classify Triangles Standard 4C.
Triangle – a three sided polygon (straight sides; closed) A B C 3 sides: 3 angles: 3 vertices: A, B, C.

Classifying Triangles Angle Measures of Triangles.
Triangles Triangle: a figure formed when 3 noncollinear points are connected by segments. Components of a triangle: Vertices: A, B, C Sides: AB, BC, AC.
Angles Acute angle (def)- angle measure less than 90° Right angle (def)- angle measure= 90° Obtuse angle (def)- angle measure greater than 90° Straight.
Angle Relationships Geometry 1.5.
Angles and Triangles. Angles A shape formed by two rays sharing a common endpoint; contains two rays and a vertex ray vertex ray—has one endpoint and.
Math I CAN find the measure of angles. I CAN construct angles.
Triangle Inequality Notes. Triangle Inequality Theorem Scalene triangle: A triangle that has no congruent (equal) sides. None of their angles are congruent.
- is a flat surface that extends in all directions. Objective - To identify angles as vertical, adjacent, complementary and supplementary. Plane.
