Describe and sketch a solid with the following properties. When illuminated by rays parallel to the z-axis, its shadow is a circ
ular disk. If the rays are parallel to the y-axis, its shadow is a square. If the rays are parallel to the x-axis, its shadow is an isosceles triangle.
1 answer:
Answer:
The solid formed is known as a conoid.
Step-by-step explanation:
The projection of the solid in XY plane is a circle of diameter D.
The projection of the solid in XZ plane is a square of length D.
The projection of the solid in YZ plane is an isosceles triangle of height D and base D.
The following picture shows all the projections and a sketch of the solid:

The two triangles are similar by SSA similarity. Option B is correct.
<h3>What is the triangle?</h3>A triangle is a three-sided polygon. It is one of the most fundamental geometric forms.
If the ratio of the sides are same as well as the one angle is common between the two triangles then in that condition there will be SSA similarity.
From the triangle ABC and DEC
The ratio of the sides is;
One angle c is common in the two triangles.
The two triangles are similar by SSA similarity.
Hence, option B is correct.
