Could the segments 7 1 7 form a triangle?
Yes. What you should watch out for is that, to form a triangle, none of the segments should be longer (or as long as) the other two segments combined. Just check whether the longest segment is longer than the sum of the other two - if it is, then you can't form a triangle.
Could segments 1 8 8 form a triangle?
No, segments 1, 8, and 8 cannot form a triangle. In order for three segments to form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side. In this case, 1 + 8 is equal to 9, which is not greater than 8. Therefore, a triangle cannot be formed.
Which figure does NOT have at least 1 pair of parallel line segment?
A triangle can't have.
What is a segment connecting the vertex and the midpoint of the opposite side of the triangle?
That would be the height when determing the area of the triangle. A= 1/2 base x height
Can the segments 9 9 1 form a triangle?
Yes the given segments would form an isosceles triangle
Could the segments 7 1 7 form a triangle?
Yes. What you should watch out for is that, to form a triangle, none of the segments should be longer (or as long as) the other two segments combined. Just check whether the longest segment is longer than the sum of the other two - if it is, then you can't form a triangle.
Could the segments 7 and 1 and 7 form a triangle?
Yes they could.
Could segments 1 8 8 form a triangle?
No, segments 1, 8, and 8 cannot form a triangle. In order for three segments to form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side. In this case, 1 + 8 is equal to 9, which is not greater than 8. Therefore, a triangle cannot be formed.

Can the segments 9 9 1 form a triangle?
Yes the given segments would form an isosceles triangle
Can the segments 9 9 and 1 form a triangle?
Yes the given segments would form an isosceles triangle
Can segments 1 8 and 8 form a triangle?
Yes, it would form a tall isosceles triangle. Add the smallest two (1+8=9 in this case). If it is greater than the longest (8 in this case) then they can form a triangle.
What is a triangle with 1 axis of symmetry?
This could be either an isosceles triangle or a right angled triangle.
Can the lengths 7 and 1 and 7 form a triangle?
Yes and it will be in the form of an isosceles triangle having two equal sides.
Is it possible to form a triangle with the lengths of 1 8 and 8?
Sure! It will be an isosceles triangle.
Can 1 8 8 form a triangle?
True
