Pick 2 triangles to classify by their angles AND sides.

A. Obtuse-Scalene

B.Right-Scalene

C.Obtuse-Scalene

D.Acute-Scalene

300

If I have three side lengths, 4.7, 5.3, and 1.24, does this make a triangle? why?

Yes, because the two smallest sides added up, are bigger than the third side

x= 32°

16= 16°

300

What is the circumference?

6.2π mm

400

Angle AEC is ________ to angle DEB

They are vertical to eachother

400

Find the missing angle and classify the triangle by sides and angles.

30˚

Scalene-Obtuse

400

The last side length of this triangle is 5. Why is this is not an incomplete triangles. Give at least reason why, and explain for at least 30 seconds.

When the two sides do not add up, that means that one side length is too small, compared to the rest of the side lengths, therefore not completing the triangle.
