Can a base angle of an isosceles triangle be an obtuse angle?
Only if you are dancing on a log in the lost forest.
How do you draw altitude on triangle?
You write the height. Draw as dashed line segment, which is perpendicular to the base, from the top vertex down to the base (or a dashed line extended from the base for an obtuse triangle). Put a right-angle symbol (small square) where this line segment intersects the base)
What is the Formula for an obtuse triangle?
The hypotneuse is squared and added to the base
An angle not congruent to the base angles of an isosceles triangle?
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
How do you calculate area of obtuse triangle?
Area = 0.5*base*altitude
Can a base angle of an isosceles triangle be an obtuse angle?

Does obtuse triangle must have greater area than an acute triangle?
yes. take an obtuse triangle that has a base of 8cm and a height of 3cm. then, take a right triangle that has a base of 3 cm and a height of 4 cm. do the math. the obtuse triangle will have a greater area. hope this helps.
How do you classify a triangle by the sizes of there angles?
All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are classed as follows:- Right angle triangle:a 90 degree angle and 2 acute angles Scalene triangle: 3 acute angles Obtuse triangle: an obtuse angle and 2 acute angles Isosceles triangle: 2 equal base angles and an apex angle Equilateral triangle: 3 equal angles each measuring 60 degrees
What are the characteristics of the different types of triangles?
All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are graded as follows:- Scalene triangle has 3 different acute angle Right angle triangle has a 90 degree angle and 2 acute angles Obtuse triangle has 1 obtuse angle and 2 acute angles Equilateral triangle has 3 equal sides and 3 equal angles of 60 degrees Isosceles triangle has 2 equal sides and 2 equal base angles
How do you draw altitude on triangle?

The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
How do you classify triangles using their attributes?
All triangles have 3 sides and 3 interior angles that add up to 180 degrees and are classified as follows:- Scalene triangle has 3 different acute angles Obtuse triangle has an obtuse angle and 2 different acute angles Right angle triangle has a 90 degree angle Isosceles triangle has 2 equal sides and 2 equal base angles Equilateral triangle has 3 equal sides and 3 equal 60 degree angles
How do you calculate area of obtuse triangle?
Area = 0.5*base*altitude
The obtuse angle of an isosceles triangle measures 120 degrees write and solve an equation to find the measure of the base angles?
Well if it has 180 degrees over all, and the two base angles have to be congruent, then the equation is 180-120=2x or each base angle is 30 degrees.
What shape has 3 right angles one obtuse angle and one reflex angle?
Just draw it out. Draw a square with a 3-4-5 right triangle abutting it, laying on its long side with it's short side against the square. The length of the base of the triangle should be about half the length of the square's side. Trace the perimeter of these two objects, and you will get a 5 sided object with: three right edges of a square, with an obtuse angle coming off the side and an acute, reflex angle at the tip of the right triangle.
What does a quadrilateral with one right angle one obtuse angle and two acute angles look like?
Somewhere between a trapezoid and a triangle. Imagine an image where the left edge is perpendicular to the base (right angle), the top declines slightly from left to right (acute angle), and the right side declines sharply from the top (obtuse) to its intersection with the base (acute). Another option would be for the top to incline as it moves away from the side forming the obtuse angle, then the other side declines even more sharply forming acute angles at intersection with the top and bottom.
