Module 5 – Real World Applications

Now Lets See about finding the Angles of this Pennant......

 The Pennant is an isosceles triangle. Remember that an isosceles triangle has two equal sides and two equal bases.



After using a protractor to measure the base angles, you discover that the angle measurements of the base angles are 74 degrees.

Remember from Module 4:Figuring Angle Measurements, that the sum of the angles of a triangle are equal to 180 degrees.

**So Let's do the math.... **

** Base Angle 1 + Base Angle 2 + Missing Angle = 180 degrees **

** 74 + 74 + ? = 180 **

**Add 74 + 74= 148 **

**Subtract <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;"> 180-148 = 32 **

**<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;"> The missing angle is 32 degrees **
