Does a pyramid have triangular faces?
It depends on the shape of the base, but yes it has at least 3 triangular faces!(yes)
An equilateral triangle is a special case of a isosceles triangle?
Yes - if you define an equilateral triangle as one in which at least two sides are equal.
Can a polygon be equilateral and equiangular but not convex?
No. A non-convex polygon must have at least one reflex angle (between 180 and 360 degrees). But by equiangularity, all the angles of the polygon would have to be reflex. On a plane surface this is not possible.
How many triangles have at least two equal sides?
equilateral triangles and isosceles ones
Is an equilateral triangle equal to an isosceles triangle?
An isosceles triangle has at least two congruent sides. An equilateral triangle has three congruent sides. So, an equilateral triangle is a special case of isosceles triangles. Since the equilateral triangle has three congruent sides, it satisfies the conditions of isosceles triangle. So, equilateral triangles are always isosceles triangles. Source: www.icoachmath.com
What solid figure has the least number of faces a triangular prism or triangular pyramid?
triangular pyramid
What ocean covers the least amount of the earth's surface?
mount k2
What surface uses the least amount of friction?
A smooth, slippery surface like ice or Teflon typically has the least amount of friction. This is because these surfaces have very low coefficients of friction, allowing objects to slide easily with minimal resistance.
Do equilateral triangles have at least two congrent sides?
Equilateral triangles have three congruent sides. That's the definition of an equilateral triangle. If it doesn't have three congruent sides, then it's not an equilateral triangle.
An equilateral triangle has at least two sides that are equal true or false?
False...an equilateral triangle has 3 equal sides.
Does a rectangular prism have at least one triangular face?
yes, it has at least three
Does a pyramid have triangular faces?
It depends on the shape of the base, but yes it has at least 3 triangular faces!(yes)
Which surface will produce least amount of friction?
A smooth surface will produce the least amount of friction compared to a rough surface. Friction is caused by the resistance when two surfaces slide against each other, and smoother surfaces have fewer microscopic irregularities that create friction. The coefficient of friction is lower for smooth surfaces.
An equilateral triangle is a special case of a isosceles triangle?
Yes - if you define an equilateral triangle as one in which at least two sides are equal.
What solid has at least one triangular face?
pyramid
Why might you want to know the dimensions of the box with the least surface area?
so you can use the least amount of paper to make the box. or wrap the box.
What figure do not have a least 1 rectangular face?
triangular prism
