# It is easy to work out the missing angles of an isosceles triangle by looking for An obtuse triangle has three different angles, with one angle greater than 90°.

A triangle cannot be right-angled and obtuse angled at the same time. Since a right-angled triangle has one right angle, the other two angles are acute. Therefore, an obtuse-angled triangle can never have a right angle; and vice versa. The side opposite the obtuse angle in the triangle is the longest. Obtuse angled triangles in real life: In

Therefore, those two angles must be degrees and degrees. Whether an isosceles triangle is acute, right or obtuse depends only on the angle at its apex. In Euclidean geometry, the base angles can not be obtuse (greater than 90°) or right (equal to 90°) because their measures would sum to at least 180°, the total of all angles in any Euclidean triangle. Obtuse Triangle. The Obtuse Triangle has an obtuse angle (an obtuse angle has more than 90°). In the picture on the left, the shaded angle is the obtuse angle that distinguishes this triangle .

A triangle may be classified by how many of its sides are of equal length. Or, it may be classified by what kind of angles it has.Types of Triangles by Length In an equilateral triangle, all three sides are the same length. Answer and Explanation: An isosceles triangle can have only one obtuse angle. An obtuse angle is an angle greater than 90 degrees and lesser than 180 degrees 2 Jul 2019 The longest side of an obtuse triangle is the one opposite the obtuse angle vertex . · An obtuse triangle may be either isosceles (two equal sides Isosceles Obtuse Triangle. We know that the obtuse triangle is a triangle in which one of its angle is greater than 90 An isosceles triangle has two edges of the same length.

An acute angle is one that measures less than 90 degrees. A scalene
An obtuse triangle is a triangle that has one obtuse angle, meaning an angle that is greater than 90 degrees but less than 180 degrees. So, for an isosceles triangle to be considered obtuse, it just has to be a triangle with two equal sides and an angle that is in between 90 degrees and 180 degrees. Triangles for Kids - Equilateral, Isosceles, Scalene, Acute Triangle, Right Triangle and Obtuse - YouTube. Yes, an obtuse triangle can be isosceles.

In the picture on the left, the shaded angle is the obtuse angle that distinguishes this triangle . Since the total degrees in any triangle is 180°, an obtuse triangle can only have one angle that measures more than 90°. Since a triangle is obtuse or right if and only if one of its angles is obtuse or right, respectively, an isosceles triangle is obtuse, right or acute if and only if its apex angle is respectively obtuse, right or acute. Properties of Obtuse Triangles The longest side of an obtuse triangle is the one opposite the obtuse angle vertex. An obtuse triangle may be either isosceles (two equal sides and two equal angles) or scalene (no equal sides or angles).

2020-06-26 · the isosceles triangle can be acute, right or obtuse, but it depends only on the vertex angle (base angles are always acute) The equilateral triangle is a special case of a isosceles triangle. Isosceles triangle formulas for area and perimeter To calculate the isosceles triangle area, you can use many different formulas. Correct answers: 3 question: Classify the following triangle.

### Given an isosceles triangle with equal sides of length $b$ and base angle $A$ $(<π/4)$. $O$ and $I$ are the circumcenter and incenter of the triangle respectively.

Correct answer: Explanation: Based on the description of your triangle, you can draw the following figure: You can do this because you know: The two equivalent sides are given. Since a triangle is degrees, you have only or degrees left for the two angles of equal size. Therefore, those two … Right Triangles. A right triangle has one 90° angle and a variety of often-studied topics: Pythagorean … An obtuse triangle is a triangle that has one obtuse angle, meaning an angle that is greater than 90 degrees but less than 180 degrees. An isosceles triangle is a triangle that has at least two equal sides.

## Possible Answers: Correct answer: Explanation: Use the Pythagorean Theorem to find the base of the right triangle. Now, because two of the angles in this triangle are the same, this is an isosceles triangle. In an isosceles triangle, the sides that are directly across from the congruent angles are also congruent.

An obtuse angle is an angle greater than 90 degrees and lesser than 180 degrees 2 Jul 2019 The longest side of an obtuse triangle is the one opposite the obtuse angle vertex . · An obtuse triangle may be either isosceles (two equal sides Isosceles Obtuse Triangle.
