Josh drew an acute isosceles triangle. He had an angle that measured 90 degrees and 2 sides that were equal. What was wrong with his drawing?
What is he had a right angle in a triangle that needs 3 angles that are each < 90 degrees.

What is 130 degrees

300
A triangle with no equal sides.
What is a scalene triangle?
300
Draw an equiangular triangle.
What is "Show teacher triangle with all angles equal."
300
A triangle with one angle measuring exactly 90 degrees.
What is a right triangle?
300
This triangle has 2 sides the same length and one right angle. Classify by both angles and sides.
What is a right isosceles triangle?
300

Fill the missing angle:
25+____+100

What is 55 degrees

400
A triangle is equilateral, so this is also true about that triangle: A) It is a right triangle. B) It is a scalene triangle. C) The triangle is equiangular. D) The triangle is obtuse.
What is the triangle is equiangular?
400

Draw a triangle with perpendicular lines. (Hint: Hopefully you're right!)

What is a right triangle drawing?

400
A triangle with the following angle measurements: 97 degrees, 40 degrees, and 43 degrees.
What is an obtuse triangle?
400
This triangle is an acute obtuse triangle. Is this possible? Why or why not?
What is not possible, because an obtuse triangle has one angle >90 degrees and an acute triangle has all 3 angles < 90 degrees.
400

A triangle that has the largest angle measuring 109 degrees, the next angle measuring 32 degress. What is the last angle? 

What is 39 degrees

500
The sides of an isosceles triangle could measure the following: A) 6", 7", 8" B) 9", 9", 9" C) 6", 9", 11" D) 6", 6.5", 7"
What is B, 9", 9", 9"?
500
Draw a triangle that is obtuse and scalene.
What is a triangle with an obtuse angle and no equal sides.
500
This triangle has one angle measuring 88 degrees.
What is an acute triangle?
500

An equilateral triangle can ALSO be an isosceles triangle. True or false, and why?

What is true, because an equilateral triangle has 3 equal sides. An isosceles triangle has ATLEAST 2 equal sides, which means it could also have 3 equal sides.
