What is the relationship between the lengths of the sides of a triangle and the measures of its interior angles?

Back

In any triangle, the largest side is opposite the largest angle, and the smallest side is opposite the smallest angle.

Front

How do you construct a perpendicular line to a given line through a point not on the line?

Back

To construct a perpendicular line, use a compass to draw arcs from the point and intersect them with the line, then connect the point to the intersection points.

Front

What is the formula for the perimeter of a triangle?

Back

The perimeter of a triangle is the sum of the lengths of its sides: P = a + b + c.

Front

What is an equilateral triangle?

Back

An equilateral triangle is a triangle in which all three sides are of equal length and all three interior angles are equal (each measuring 60 degrees).

Front

What happens to the coordinates of a point when it is reflected over the line y = -x?

Back

When a point (x, y) is reflected over the line y = -x, its new coordinates become (-y, -x).

Front

What is the significance of the centroid in a triangle?

Back

The centroid is the point where the three medians of a triangle intersect, and it is also the center of mass of the triangle.

Front

How do you find the length of a segment using construction?

Back

To find the length of a segment using construction, you can use a ruler to measure the segment directly or use a compass to replicate the length.

Front

What is the definition of a quadrilateral?

Back

A quadrilateral is a polygon with four sides, four vertices, and four angles.

Front

What is the relationship between the angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

How do you determine the greatest angle in a triangle based on side lengths?

Back

The greatest angle in a triangle is opposite the longest side.
