4-1 Pumpkin Problems
This pumpkin needs to be carved into a Jack-O-Lantern. Follow the directions below to carve it.
1. The pumpkin’s LEFT EYE must be scalene. Show me it is scalene by putting measures on it’s sides.2. The pumpkin’s RIGHT EYE must be isosceles. Show me it is isosceles.3. The pumpkin’s NOSE must be equilateral. Show me it is equilateral.4. Finally, the pumpkin needs a mouth. Solve the following problem. The FINAL answer will be how many teeth the pumpkin should have.
Find the measure of each side of equilateral triangle RST with RS = 2x + 2, ST = 3x, and TR = 5x - 4.
5. Color in the eyes, nose, and mouth in BLACK. Make sure you check with me to see if you are correct FIRST! Then, color the rest of your Jack-O-Lantern however you wish!
Classifying TrianglesDefine the following types of triangles, then draw a picture of each.
Equilateral Scalene Right
Obtuse Equiangular Isosceles
Acute Acute Isosceles Equilateral Equiangular
Right Scalene Acute Scalene Right Isosceles
Classify each triangle by angles AND sides. You will have 2 answers for each!

4-1 Practice
5
Classify each triangle as acute, equiangular, right or obtuse.

Discovering the Angle Sum TheoremCut out the colored triangle. CAREFULLY tear (do not cut) off angles A, B, and C. Line up the angles so that they are adjacent to each other on the line below. After your placement has been checked, glue your angles in place. Then answer the questions at the bottom of the sheet.
1. When you placed the angles of the triangle on the line beside each other, what did you notice?
2. If those 3 angles form a LINE, what must the sum of the interior angles of a triangle be? (What do all 3 of the angles add up to?)
Angle Sum Theorem- <A + <B + <C =
7
Discovering the Exterior Angle TheoremCut out the colored triangle. Tear off angle A and B. Glue the two angles next to each other at the vertex of <ACD. They should be a perfect fit.
