ice cream cones, cat ears, pencil tip and guitar pick are sort of triangular shaped.
sorry if that's not enough but you can look some up on Google. :)
An acute angle can be found in the shape of a corner in a room, where two walls meet to form an angle that measures less than 90 degrees.
an acute triangle is a triangle that has?
If two angle bisectors of a triangle are congruent, then the triangle is isosceles. This is because the angle bisectors of a triangle are concurrent and the angle bisectors of a triangle that are congruent divide the opposite sides of the triangle into two equal segments. So if two angle bisectors are congruent, the sides opposite those angles are also equal, making the triangle isosceles.
An acute triangle is a triangle in which all three angles are less than 90 degrees.
Actually, the orthocenter of a triangle is the point where the three altitudes of the triangle intersect. The altitudes are perpendicular lines drawn from each vertex to the opposite side. The angle bisectors of a triangle intersect at the incenter, not the orthocenter.
A pennant is a real life example of an isosceles triangle.
An umbrella.
Any pythagorean triangle with unequal legs.
An equilateral triangle is a triangle in which all three sides are equal. The yield sign on highways is an equilateral triangle.
The only example that I can think of is a slide.
The yield signs on highways are equilateral.
the peak of a roof often forms an obtuse triangle.
A real life example of a right-angled triangle would be a ladder leaning against a wall. And a acute triangle is an example of a umbrella. Some types of an umbrella are divided into a few sections using triangles edit by: A.B
The roof truss of a building with a low ridge roof.
people playing sports-angle of legs, arm, ect
A Spy Plane is an example of Acute Triangle.... >> njoy
A right angle triangle always has 2 acute angles within it.
