How do you draw an obtuse triangle?
Construction
- Draw a horizontal line segment from point to by a ruler.
- Use protractor and mark a point at an obtuse angle.
- Take a compass and set it to any length by a ruler.
- Finally, join the points and by a line for completing the construction of a triangle geometrically.
How do you find the base and height of an obtuse triangle?
For an obtuse triangle, any side of the figure can be considered the base, so measure one of the sides and insert it into the formula area = 1/2 x (base x height). For example, if the base is 3 and the height is 6, your calculation would be 1/2 times 3 times 6 equals 9.
What is the rule for obtuse triangle?
In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°. Here, the triangle ABC is an obtuse triangle, as ∠A measures more than 90 degrees. Since, ∠A is 120 degrees, the sum of ∠B and ∠C will be less than 90° degrees.
How do I find the height of a triangle?
How to find the height of a triangle – formulas
- area = b * h / 2 , where b is a base, h – height.
- so h = 2 * area / b.
How do I find the height of an acute triangle?
Plug your values into the equation A=1/2bh and do the math. First multiply the base (b) by 1/2, then divide the area (A) by the product. The resulting value will be the height of your triangle!
What do you call a triangle with no equal sides?
Scalene. A scalene triangle has three different angles and none of its sides are equal in length.
Is it possible to draw an obtuse isosceles triangle?
It is not possible to draw a triangle with more than one obtuse angle. Note: It is possible for an obtuse triangle to also be scalene or isosceles.
Where is the height located on an acute triangle?
When a triangle is a right triangle, the altitude, or height, is the leg. If the triangle is obtuse, then the altitude will be outside of the triangle. If the triangle is acute, then the altitude will be inside the triangle.
How do you find height of a triangle?
Can a triangle have one obtuse and right angle?
No, a triangle cannot have an obtuse and a right angle.
