What is the definition of a triangle?

A triangle is a geometric shape with three sides, three vertices, and three angles. It is a polygon that is formed by connecting three non-collinear points.

How many sides does a triangle have?

A triangle has three sides.

What is the sum of the interior angles of a triangle?

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

What is an equilateral triangle?

An equilateral triangle is a triangle with three equal sides and three equal angles, each measuring 60 degrees.

What is an isosceles triangle?

An isosceles triangle is a triangle that has two equal sides and two equal angles. The sides opposite the equal angles are also equal in length.

What is a scalene triangle?

A scalene triangle is a type of triangle that has three unequal sides and three unequal angles. This means that none of the sides or angles are the same size in a scalene triangle, making it distinct from equilateral and isosceles triangles which have equal sides and angles.

What is the Pythagorean Theorem and how is it used in triangles?

The Pythagorean Theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. This theorem is used to calculate the length of one side of a right triangle when the lengths of the other two sides are known. By applying this formula, we can find missing side lengths, determine whether a triangle is a right triangle, and solve various geometric problems involving right triangles.

How do you find the area of a triangle?

To find the area of a triangle, you can use the formula Area = 1/2 * base * height, where the base is the length of the bottom side of the triangle and the height is the perpendicular distance from the base to the opposite vertex. Simply plug in the values of the base and height into the formula to calculate the area of the triangle.

What is a right triangle?

A right triangle is a type of triangle that has one angle measuring 90 degrees, known as the right angle. This angle is formed where the two perpendicular sides of the triangle intersect, creating the longest side, called the hypotenuse, and two shorter sides called the legs. The Pythagorean theorem can be used to calculate the lengths of the sides of a right triangle, making it a fundamental concept in geometry and trigonometry.

How can you classify triangles based on their angles?

Triangles can be classified based on their angles as either acute, right, obtuse, or equiangular. Acute triangles have all three angles less than 90 degrees, right triangles have one angle equal to 90 degrees, obtuse triangles have one angle greater than 90 degrees, and equiangular triangles have all three angles equal to 60 degrees.
