Is an acute angled triangle a regular shape?
Not necessarily. But a regular triangle must be acute angled.
What is the effect if people use other shape than triangle in building a sculpture and etc?
when building a structure, triangles are a must because they are stable. without changing the length of the struts/ties or detaching the joints, it is impossible to deform a triangle. a square, however, can deform simply by changing the angles of its corners, going from a square to a rhombus. the same applies for any other polygon with more than 3 sides, although they do not become rhombi.
What shape has three sides that are not equal but have a right angle?
with the three sides you know it will be a triangle, it is a right triangle, it is not an equilateral triangle or an isosceles triangle... so it must be a right scalene triangle
Are there any 3 sided shapes besides the triangle?
No because a polygon must have 3 or more sides and the next shape after the triangle is a 4 sided quadrilateral
Can a triangle have 1 or more obtuse angles?
NO!! The question is: Can a triangle have one OR more obtuse angles? A triangle can have one obtuse angle, the other two must be acute in order to close the shape. An obtuse angle is greater than 90 degrees and to make a sum of the 180 degrees in a triangle, the sum of the other two must equal <90 degrees. Since the question asked ...one or more... and one of the two options is correct, the answer must be: Yes, it is possible to have one OR more obtuse angles in a triangle.
What is a shape that must be a 90 degrees angle?
A right angle triangle must have a 90 degree angle and two acute angles.
How can you determined a figure is shape like a right triangle?
it must have three side and point no more no less
Can an acute triangle be obtuse?
No, they must be either one or the other.
What shape is 14 centimeters and 3 centimeters and 8 centimeters?
If it only has those 3 sides then it must be a triangle. As all its sides are different lengths it's a scalene triangle.
How many sides does a shape have to have to be a parallelogram?
A shape must have 4 sides in order to be a parallelogram (minus other defining characteristics a shape must have to be a parallelogram).
What else must be true about the sides of the triangles in order for the triangles to be similar?
All three ratios of a side of one triangle to the corresponding side of the other triangle must be the same.
How do you find volume and area of a triangle?
A triangle has no volume - it is a 2-dimensional shape only. To find the area, multiply the base times the height, then divide by 2. The base is any side of the triangle; the height must be measured perpendicular to the base.
