Which statement is a good definition? a. parallel lines are lines that do not intersect b. skew lines are lines that do not intersect c. a square is a rectangle with four congruent sides. d. right angles are angles formed by two intersecting lines

Option (C) is correct.

Step-by-step explanation:

A square is a type of quadrilateral in which all the sides are equal and each angle is 90°.

Parallel lines are the lines that do not intersect each other but their perpendicular distance between two lines is constant. Skew lines are not parallel and right angles are perpendicular to each other.Hence, Square is a form of rectangle in which all the four sides are congruent.

Thus, the correct answer is option (C).

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
