Answer:
Spectrum Math Grade 2 Chapter 7 Pretest Answer Key_1
A rectangular prism is a three-dimensional shape, having six faces, where all the faces (top, bottom, and lateral faces) of the prism are rectangles such that all the pairs of opposite faces are congruent.

square pyramid
Spectrum Math Grade 2 Chapter 7 Pretest Answer Key 2
Answer:
Spectrum Math Grade 2 Chapter 7 Pretest Answer Key_2
A three-dimensional geometric shape having a square base and four triangular faces/sides that meet at a single point (called a vertex) is called a square pyramid. It is called a pentahedron, due to its five faces.  A square pyramid has:
– An apex: top vertex or point of the pyramid
– A Base in a square shape
– Four triangular faces

sphere

Answer:
Spectrum Math Grade 2 Chapter 7 Pretest Answer Key_3
the sphere is a geometrical figure that is round in shape. The sphere is defined as a three-dimensional space. The sphere is three dimensional solid, that has surface area and volume. Just like a circle, each point of the sphere is at an equal distance from the centre.

Spectrum Math Grade 2 Chapter 7 Pretest Answer Key 4
Answer:
Spectrum Math Grade 2 Chapter 7 Pretest Answer Key_4
– square has four equal sides and angles.
– Circle has no shape.
– Triangle has three sides.
– Rectangle has four sides and opposite sides are equal.
– Pentagon has five equal sides.
– Hexagon has six equal sides.

Answer the questions.

Which shape has 4 equal sides?
Answer: Square.
– Square is a regular quadrilateral, which has all four sides of equal length and all four angles are also equal. The angles of the square are at right-angle or equal to 90 degrees. Also, the diagonals of the square are equal and bisect each other at 90 degrees. A square can also be defined as a rectangle where two opposite sides have equal lengths.
Properties:
– All four interior angles are equal to 90°
– All four sides of the square are congruent or equal to each other
– The opposite sides of the square are parallel to each other
– The diagonals of the square bisect each other at 90°
– The two diagonals of the square are equal to each other
– The square has 4 vertices and 4 sides

Which shape has 4 triangular Spectrum Math Grade 2 Chapter 7 Pretest Answer Key 5 faces and 1 square Spectrum Math Grade 2 Chapter 7 Pretest Answer Key 6 face?
Answer: Square pyramid
A three-dimensional geometric shape having a square base and four triangular faces/sides that meet at a single point (called a vertex) is called a square pyramid. It is called a pentahedron, due to its five faces.  A square pyramid has:
– An apex: top vertex or point of the pyramid
– A Base in a square shape
– Four triangular faces

Which shape has 3 total angles?
Answer: Triangle.
A triangle is a polygon with three sides having three vertices. The angle formed inside the triangle is equal to 180 degrees. It means that the sum of the interior angles of a triangle is equal to 180°. It is a polygon having the least number of sides.
Properties:
– The sum of the interior angles of a triangle is 180 degrees
– When two sides of a triangle are added, it is always greater than the third side
– Similarly, if the two sides of a triangle are subtracted, it is always less than the third side
– Two triangles are said to be similar if the corresponding angles are congruent and the corresponding side lengths are proportional.

hexagon
Answer:
Spectrum Math Grade 2 Chapter 7 Pretest Answer Key_7
A hexagon is a two-dimensional geometrical shape that is made of six sides, having the same or different dimensions of length. Some real-life examples of the hexagon shape are a hexagonal floor tile, pencil cross-section, clock, honeycomb, etc. It can be either regular (with 6 equal side lengths and equal angles) or irregular (with 6 unequal side lengths and angles).
Properties:
– It has six sides, six edges, and six vertices.
– All the side lengths are equal or unequal in measurement.
– All the internal angles are equal to 120° each in a regular hexagon.
– The sum of the internal angles is always equal to 720°.
– All the external angles are equal to 60° each in a regular hexagon.
– The sum of the exterior angles is equal to 360°.
