We can use a protractor and verify the same. Learn Practice Download. Obtuse Angle Obtuse angle is one of the types of angles that form on the plane surface.
What Is an Obtuse Angle? Obtuse Angle Degree 3. Examples of Obtuse Angles 4. Obtuse Angle of a Triangle 5. Obtuse Angles of a Rhombus 6. Obtuse Angles of a Parallelogram 7. Obtuse Angle Examples Example 1: Identify the obtuse angles from the following figures.
Example 2: At what times, in the clocks shown below, an obtuse angle is formed? Solution: We can observe that in all instances, an obtuse angle is formed between the hour's hand and the minutes' hand of the clock. At , the hour hand is at 5 and the minute hand is at At , the hour hand is at 8 and the minute hand is at At , the hour hand is at 10 and the minute hand is at 3. At , the hour hand is slightly above and the minute hand is at 8.
Therefore, an obtuse angle is formed at , , , and Solution: In an obtuse triangle, the sum of the square of two sides should be less than the square of the greatest side i. Want to build a strong foundation in Math? It has one of its vertex angles as obtuse and other angles as acute angles i. An obtuse triangle can also be called an obtuse-angled triangle. In general, an obtuse triangle can be a scalene triangle or isosceles triangle but not an equilateral triangle.
The circumcenter and orthocenter lie outside the triangle while the centroid and incenter come inside the obtuse triangle. The longest side of a triangle is considered to be the opposite side of the obtuse angle. To find if a triangle is obtuse, we can look at the angles mentioned. Learn Practice Download. Obtuse Triangle An obtuse triangle is a triangle with one interior angle measure greater than 90 degrees. What Is an Obtuse Triangle? Obtuse Angled Triangle Formula 3. Obtuse Angled Triangle Properties 4.
Obtuse Angled Triangle Examples Example 1: Which of the following angle measures can form an obtuse-angled triangle? Solution: The sides of an obtuse triangle should satisfy the condition that the sum of the squares of any two sides is lesser than the square of the third side.
