Geometry enthusiasts, hold onto your protractors! We’re about to dive into the captivating world of Obtuse Triangles. But first, let’s break down the mystery behind these fascinating shapes. An obtuse triangle is a daring adventurer with one angle that dares to go beyond 90°. The area of this audacious figure can be calculated using the following formula:
Area = 1/2 * base * height
With the formula unveiled, let’s unravel more secrets.

FAQs on Obtuse Triangle Calculator
- What is an obtuse triangle? An obtuse triangle is a triangle with one angle greater than 90°.
- How do you calculate the area of an obtuse triangle? The area is calculated using the formula: 1/2 * base * height.
- What is the difference between an obtuse triangle and a right triangle? A right triangle has one angle of exactly 90°, while an obtuse triangle has one angle greater than 90°.
- Can all triangles be classified as obtuse, acute, or right? Yes, all triangles can be classified as one of these three types based on their largest angle.
- What is the significance of obtuse triangles in geometry? Obtuse triangles are important for understanding the properties of different types of triangles and their applications.
- How can you identify an obtuse triangle? If a triangle has one angle that is greater than 90°, it is an obtuse triangle.
- Is it possible for an obtuse triangle to have an angle greater than 180°? No, the sum of all angles in any triangle is always 180°.
- Can an obtuse triangle be equilateral? No, an equilateral triangle has all angles equal to 60°, so it cannot be obtuse.
- How does the area of an obtuse triangle compare to other triangles? The area of an obtuse triangle depends on its base and height, not its angle measurements.
- Why is it harder to calculate the area of an obtuse triangle compared to a right triangle? It can be more challenging because the height of an obtuse triangle can fall outside of the triangle, which is not the case with a right triangle.
