14.
Bangun yang memiliki 3 buah sudut
dan 3 buah sisi adalah ....
Correct Answer
C. Segitiga
Explanation
A triangle is a polygon with three sides and three angles. It is the only option given that fits this description. A square has four sides and four angles, while a rectangle has four sides but only two pairs of congruent angles. Therefore, the correct answer is a triangle.
15.
Nama bangun diatas adalah ....
Correct Answer
C. Trapesium
Explanation
The given shape is a trapezium because it has only one pair of parallel sides. A trapezium is a quadrilateral with one pair of parallel sides. In this case, the top and bottom sides of the shape are parallel to each other, while the other two sides are not. Therefore, the correct answer is trapesium.
16.
Bangun jajar genjang memiliki ....

17.
Bangun lingkaran memiliki sisi sebanyak ....
Correct Answer
B. 1 buah
Explanation
The correct answer is "1 buah" because a circle does not have sides. A circle is a two-dimensional shape that is defined by a curved line called the circumference. It does not have any straight sides like other polygons such as triangles, squares, or rectangles. Therefore, it is incorrect to say that a circle has any number of sides.
18.
Bangun diatas dibentuk dari rangkaian bangun.... .
Correct Answer
B. Segitiga
Explanation
The given answer, "Segitiga" (triangle), is correct because the question states that the structure is formed from a series of shapes. Among the options provided, a triangle is the only shape that can be used to form a structure by connecting its sides. A square (segiempat) and a rectangle (persegi panjang) have straight sides that can be connected to form a structure, but they cannot create the angles and slopes that a triangle can. Therefore, a triangle is the most suitable shape to form the given structure.
19.
Nama bangun di atas adalah ....
Correct Answer
C. Jajar genjang
Explanation
The given shape is a parallelogram with opposite sides parallel and equal in length. It has four sides and opposite angles are equal. Therefore, the correct answer is "Jajar genjang" which translates to "parallelogram" in English.

22.
Buku tulis dan meja berbentuk ....
Correct Answer
B. Persegi panjang
Explanation
The correct answer is "Persegi panjang" because a book and a table are both rectangular in shape, which is characteristic of a rectangle. A trapezium has only one pair of parallel sides, which does not match the given objects. A circle is a completely different shape and does not resemble a book or a table. Therefore, the most suitable option is "Persegi panjang" or rectangle.
23.
Segi empat memiliki sisi-sisi yang ....
Correct Answer
