What is a triangle with 2 perpendicular sides?

What is a triangle with 2 perpendicular sides?

Only one type of triangle, the right triangle, does have two perpendicular lines. Right triangles always contain a right angle created by two perpendicular sides.

What is a triangle with two sides called?

A triangle with all sides equal is called equilateral, a triangle with two sides equal is called isosceles, and a triangle with all sides a different length is called scalene.

What kind of triangle has angles 71 63 46?

Acute Triangles An acute triangle is a triangle whose angles are all acute (i.e. less than 90°). In the acute triangle shown below, ∠a, ∠b and ∠c are all acute angles. Example 1: A triangle has angles 46°, 63° and 71°.

What do you call a triangle with at least two of its sides are congruent?

Isosceles triangles have at least two congruent sides and at least two congruent angles. The congruent sides, called legs, form the vertex angle.

What is triangle and types of triangle?

The six types of triangles are: isosceles, equilateral, scalene, obtuse, acute, and right. An isosceles triangle is a triangle with two congruent sides and one unique side and angle. An equilateral triangle is a triangle with three congruent sides and three congruent angles.

What do you call a triangle that has 90 degrees angle?

From Wikipedia, the free encyclopedia. A right triangle (American English) or right-angled triangle (British), or more formally an orthogonal triangle (Ancient Greek: ὀρθόςγωνία, lit. ‘upright angle’), is a triangle in which one angle is a right angle (that is, a 90-degree angle).

Which is a right triangle with a perpendicular line?

Perpendicular lines create interesting properties and relationships in geometry, the following are some of them: • A triangle is a right triangle if 2 sides of the triangle are perpendicular. In the diagram above, triangle ABC is a right triangle with right angle at vertex B because sides AB and BC are perpendicular.

When does a triangle have a right angle?

• A triangle is a right triangle if 2 sides of the triangle are perpendicular. In the diagram above, triangle ABC is a right triangle with right angle at vertex B because sides AB and BC are perpendicular. • In plane geometry, there can be only one line drawn through a given point not on a given line that is perpendicular to the given line.

Are there any rules about perpendicular lines in geometry?

Rules involving perpendicular lines Perpendicular lines create interesting properties and relationships in geometry, the following are some of them: • A triangle is a right triangle if 2 sides of the triangle are perpendicular.

Which is a right triangle with right angle at vertex B?

In the diagram above, triangle ABC is a right triangle with right angle at vertex B because sides AB and BC are perpendicular. • In plane geometry, there can be only one line drawn through a given point not on a given line that is perpendicular to the given line.
