100
part of a line containing two end points.
What is a line segment?
100
the triangle has a right angle the triangle has no congruent sides
What is right scalene?
100
less than 90 degrees
What is acute?
100
x+50+53=180
What is 77 degrees?
100
Will the sides of 1, 2 and 3 make a triangle? Explain your answer.
What no, 1 + 2 = 3 and 3 is equal to 3; so no the sides will not make a triangle.
200
formed by three line segments that intersect only at their end points.
What is a triangle.
200
the triangle has three acute angles the triangle has two congruent sides
What is acute isosceles triangle?
200
more than 90 degrees
What is obtuse?
200
30 + 120 + x = 180
What is 30 degrees?
200
12 ft, 18 ft, and 16 ft Will this form a triangle? Explain why or why not?
What is yes. 12 + 18 = 30 ; 30 is longer than 16 so yes the given sides will made a triangle.
300
180 degrees
How many degrees are in a triangle?
300
all sides are the same length all angles are acute
What is acute equilateral?
300
a 90 degree angle
What is a right angle?
300
what is the measures of the angles in the ratio 1:6:8
What is x = 12? What is 12 degrees, 72 degrees, and 96 degrees ?
300
What is a possible measure of the third side of a triangle with the given lengths of : 30 mm and 28 mm
What is 57 mm?
400
the point where the segments of a triangle intersect
What is the vertex?
400
one angle is more than 90 degrees triangle has no congruent sides
What is obtuse scalene triangle?
400
no congruent sides
What is scalene?
400
2x + x + x = 180 what is x? what is the measures of the angles in the triangle?
What is x = 45 degrees? and what is 45 degrees, 45 degrees, and 90 degrees?
400
Will the sides of 4, 5 and 8 make a triangle? Explain
What is yes, 4 + 5 is 9 and 9 is longer than the third side of 8 so yes, it will make a triangle.

one right angle no congruent sides
What is right scalene triangle?
500
an angle that is 180 degrees
What is a straight angle?
500
4x + 3x+ 13x = 180 What is x? What is the measures of the angles in the triangle?
What is x=9 and what is 27, 36, and 117 degrees?
500
the sum of the length of any two sides of a triangle must be longer than the third side to be a triangle
What is triangular inequality?
