What is the definition of a triangle?

• A polygon with three edges and three vertices.

• A shape with four equal sides.

• A closed figure with two parallel sides.

• A three-dimensional shape with six faces.

What is the relationship between the angles in a triangle?

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

• The sum of the interior angles in a triangle is always 90 degrees.

• The sum of the interior angles in a triangle can vary depending on the type of triangle.

• The sum of the interior angles in a triangle is always 360 degrees.

What is the definition of congruent triangles?

• Triangles that have the same size and shape, meaning their corresponding sides and angles are equal.

• Triangles that have different sizes but the same shape.

• Triangles that have the same area but different angles.

• Triangles that are similar but not congruent.

What is the difference between acute, obtuse, and right triangles?

• Acute triangles have all angles less than 90 degrees, obtuse triangles have one angle greater than 90 degrees, and right triangles have one angle equal to 90 degrees.

• Acute triangles have one angle greater than 90 degrees, obtuse triangles have all angles less than 90 degrees, and right triangles have two angles equal to 90 degrees.

• Acute triangles have one angle equal to 90 degrees, obtuse triangles have all angles less than 90 degrees, and right triangles have one angle greater than 90 degrees.

• Acute triangles have all angles equal to 60 degrees, obtuse triangles have one angle equal to 120 degrees, and right triangles have one angle equal to 90 degrees.

What is the formula for the area of a triangle?

• Area = @@rac{1}{2} imes base imes height@@

• Area = base + height

• Area = base imes height

• Area = @@rac{1}{3} imes base imes height@@

What is the definition of a midpoint?

• The point that divides a segment into two equal parts.

• The point that marks the end of a segment.

• The point that is equidistant from the endpoints of a segment.

• The point that represents the average of two endpoints.

What is a perpendicular bisector?

• A line that divides a segment into two equal parts at a 90-degree angle.

• A line that connects two points without any angle.

• A line that intersects another line at any angle.

• A line that divides a segment into two unequal parts.

What is the definition of an angle bisector?

• A line that intersects two angles.

• A ray that divides an angle into two equal angles.

• A segment that connects two points on a circle.

• A point where two lines meet.
