• 🔺 A triangle can have three altitudes, each drawn from a different vertex.
• ❓ Altitudes are parallel to each other.
• 🙃 Altitudes can have different lengths in a triangle with unequal sides.
• 🔺 Altitudes are used to calculate the area and properties of a triangle.
• 🗯️ The altitude drawn from a right angle vertex of a right triangle coincides with the hypotenuse.

Questions & Answers

Q: What is altitude in the context of a triangle?

Altitude in the context of a triangle refers to the height of the triangle, which is determined by a line drawn perpendicular to a side of the triangle from a vertex.

Q: How do you measure the height of a triangle?

The height of a triangle is measured by drawing a line perpendicular to a side of the triangle from a vertex. This line is called the altitude.

Q: Can the height of a triangle vary?

Yes, the height of a triangle can vary based on the perspective from which it is viewed. When the triangle is rotated or looked at from different angles, the height may appear different.

Q: How many altitudes can a triangle have?

A triangle can have three altitudes since it has three vertices. Each altitude is drawn from a different vertex and is perpendicular to the opposite side.

Summary & Key Takeaways

• Altitude is the height of a triangle and is determined by a line drawn perpendicular to a side of the triangle.

• The height of a triangle can vary based on the perspective from which it is viewed.

• A triangle can have three altitudes, each drawn from a different vertex.
