Answer: A
a quadrilateral with all four angles right
Step-by-step explanation:
A quadrilateral is a rectangle if a quadrilateral has all four angles right,
a parallelogram with congruent sides
a quadrilateral with diagonals that are congruent and bisect each other
a quadrilateral with all congruent angles. Because a rectangle possesses 2 pairs of parallel sides, 4 right angles at 90°. It has opposite sides which
are parallel and congruent. And all its angles are congruent.
But a quadrilateral with all four angles right is a description that does NOT guarantee that a quadrilateral is a rectangle. Because this description is also applicable to a square.
Answer: The measure of AC is 32.
Explanation:
It is given that the Points B, D, and F are midpoints of the sides of ΔACE. EC = 38 and DF = 16.
The midpoint theorem states that the if a line segments connecting two midpoints then the line is parallel to the third side and it's length is half of the third side.
Since F and D are midpoints of AE and EC respectively.
So by midpoint theorem length of AC is twice of DF.
Therefore, the length of AC is 32.

Answer:
line 1 intersects line 4
Step-by-step explanation:
If line 2 intersects 1 and 3, but 1 does not intersect 3, then lines 1 and 3 are parallel.
Similarly, if line 3 intersects lines 2 and 4, but 2 does not intersect 4, then lines 2 and 4 area parallel.
If 1 and 3 are parallel, and 2 and 4 are parallel, then the fact that 2 intersects 3 means 1 intersects 4.
