Applying properties of triangles

If 4, 6, 12 form a triangle, state whether the triangle will be acute, obtuse, or right.

• Acute

• Obtuse

• Right

• These lengths will NOT make a triangle.

5.In ΔBCD, m∠B = 85° and m∠C = 75°. Which statement about the sides of ΔBCD must be true?

• DC > BD > BC

• BD > BC > DC

• BC > BD > DC

• BC > DC > BD

Name the sides from largest to smallest.

• AB, AC, BC

• AB, BC, AC

• AC, AB, BC

• BC, AB, AC

• BC, AC, AB

4. Order the side lengths from smallest to largest from the given triangle?

• BC < AB < CA

• CA < AB < BC

• CA < BC < AB

• AB < CA < AB

Order the sides from longest to shortest.

• WX, XV, WV

• WX, WV, XV

• WV, XW, XV

• WV, XV, WX

The lengths of the three sides of a right triangle are 2.5, 6.5, and 6. Which side is the hypotenuse?

• 6.5

• 2.5

• 6

6

• A
• B
• C
• D

List the side lengths from shortest to longest for the diagram.

• L, K, M

• M, L, K

• K, M, L

• L, M, K

Find the order of the sides from shortest to longest.

• XY > XZ > ZY

• ZY < XZ < XY

• ZY > XZ > XY

• XY < XZ < ZY

Use your EdPuzzle notes to fill in the blank.

The largest side is ________________ the largest angle.
