Which statements are true about triangle XYZ? Select three options.XY measures units. YZ measures units. ZX measures units. XYZ is a right triangle. XYZ is a scalene triangle.
First, second and fourth options are true about triangle XYZ.
XY measures units.
YZ measures units.
ZX measures units.
XYZ is a right triangle.
What is right triangle?
A triangle in which one of the interior angles is 90° is called a right triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base.
Given X (-1, 5), Y (4, 4), Z (-2, 0)
Distance between two points D =
So, XYZ is a right triangle.
So, the first, second and fourth options are correct.

Which of the following is a polyhedron? Check all that apply.A. Prism B. Pyramid C. Cone D. Polygon
A polyhedron is three dimensional solid that only has flat faces. It contains vertices and straight edges. From the choices, the solids that would be considered as polyhedron are prism and pyramid. A cone cannot be considered as such since it containsa round surface. A polygon is a two dimensional shape thus it does not satisfy the condition of a polyhedron.
The Prism and Pyramid is a typical example of polyhedron. That is optionA and B.
A polyhedron is any solid that has a three dimensional shape with all its sides flat. It is made up of different polygons that join together.
These polyhedron are made up of three parts:
The face: They are the flat surfaces
The edge: The region where two flat surfaces meet
The vertex: The point of intersection of the edges of the polyhedron.
Examples of polyhedron are the Prism and Pyramid. The prisms have flat faces and is made up of rectangles while the pyramids is made up of triangles and different polygons.
Therefore, the Prism and Pyramid is a typical example of polyhedron.
