Waxaan qirayaa in dhammaan murabba'aha (prisms) ay leeyihiin laba weji isku mid ah oo geeso badan leh oo isbarbar socda (saldhigyada), iyadoo wejiyada kale ay yihiin isbarbar yaal (parallelograms) oo isku xira geesaha u dhigma ee saldhigyada.

Introduction

In this lesson: I can appreciate that all prisms have two congruent polygonal parallel faces (bases) with parallelogram faces joining the corresponding vertices of the bases. Prisms are 3D shapes with a cross-section that is a uniform polygon. All prisms will have a pair of parallel faces that are congruent.

Prisms are 3D shapes with a cross-section that is a uniform polygon. All prisms will have a pair of parallel faces that are congruent. This polygon cross section is often used to name the prism. The sides connecting the bases are parallelograms.

Quizzes

  1. 1. Which of these polygons has exactly six sides?

    • quadrilateral
    • pentagon
    • Correct answer:hexagon
    • octagon
    • polygon

  2. 2. The front face of this cuboid is parallel to which other face?

    • top face
    • bottom face
    • left face
    • right face
    • Correct answer:back face

  3. 3. The front and right faces of this cuboid have equal area. Which faces of this cuboid are congruent to the front face?

    • top face
    • bottom face
    • Correct answer:left face
    • Correct answer:right face
    • Correct answer:back face

  1. 1. Which of these 3D shapes are prisms?

    • Correct answer:a
    • b
    • Correct answer:c
    • d

  2. 2. This 3D shape is a prism. The base face and cross-section shown were used to help identify this shape as a prism. Which of these statements must be true?

    • Correct answer:The base face and cross-section must be parallel to each other.
    • The base face and cross-section must be perpendicular to each other.
    • Correct answer:The base face and cross-section must be congruent to each other.
    • The base face and cross-section must be equidistant to each other.
    • The base face and cross-section must both be parallelograms.

  3. 3. Which of these names are appropriate for this prism?

    • isosceles hexagonal prism
    • Correct answer:hexagonal prism
    • regular hexagonal prism
    • Correct answer:irregular hexagonal prism
    • Correct answer:right hexagonal prism

  4. 4. Which of these words can used as part of the name of this prism?

    • right
    • Correct answer:oblique
    • parallelogram
    • Correct answer:trapezium
    • Correct answer:isosceles

  5. 5. Alex says: "This prism is a rectangular prism, because this face is a rectangle". Which of these statements is correct?

    • Alex is correct because parallel cross-sections to this face are all rectangles.
    • Correct answer:Alex is incorrect because this is not the face that is the cross-sectional base.
    • Correct answer:This prism is a right angled triangular prism.
    • This prism is definitely a right prism because there is a right angle.
