    Sec. 9.4 Sec. 9.4 Presentation Transcript

    • Learning Target:Students will learn how to classify triangles using their angles measures and by using their side lengths.
    • Remind me what the degrees are of an acute, obtuse, right and straight angle.
    • There are two main ways to classify triangles… Either by it’s angles or it’s sides.
    • Classifying Triangles by Angleshttp://kensmathworld.com/videos/classifying.png
    • Equilateral Triangle:All three sides of the triangle are the same length.http://www.mathwarehouse.com/geometry/triangles/images/equilateral-tiangle.jpg
    • Isosceles Triangles:Two sides of the triangle have the same lengths.http://image.wistatutor.com/content/feed/u984/isosceles.jpg
    • Scalene Triangle:All three sides of the triangle have different lengths.http://www.printable-math-worksheets.com/images/Scalene_Triangle.gif

    • Classify the triangle by its angles.Classify the triangle by its sides.Examples on pg. 472
    • How many degrees are in a triangle?
    • How many degrees are in a triangle?A: Every triangle, no matter the size or configuration, is made up of 180 degrees.
    • Tell whether the three angle measures could be the measures of a triangle. Justify your answer.1.) 10, 70, 802.) 18, 23, 139
    • Tell whether the three angle measures could be the measures of a triangle.1.) 10, 70, 80 – No because the sum of the angles are 160 degrees.2.) 18, 23, 139 – Yes because the sum of the angles are 180 degrees.
    • Can you classify triangles using their angles measures and by using their side lengths?
