An angle that is smaller than a right angle is called: — An acute angle.An acute angle is smaller than 90°. Obtuse is larger than 90°. Right angle is exactly 90°.
How many faces does a pyramid with a square base have? — 5.A square pyramid has 1 square base + 4 triangular faces = 5 faces total.
A cylinder has how many faces in total (counting curved surfaces)? — 2 flat + 1 curved = 3.A cylinder has 2 circular flat faces (top and bottom) + 1 curved surface wrapping around.
What angle is formed by the hands of a clock at 3:00? — Right angle (90°).At 3:00, the minute hand points to 12 and hour hand to 3 — they form a perfect right angle (90°).
A shape has 8 sides and 8 angles. What is it called? — Octagon.Octagon = 8 sides and 8 angles. Octo means eight.
Which 3D shape has triangular faces only (all faces are triangles)? — Triangular pyramid (tetrahedron).A triangular pyramid (tetrahedron) has 4 triangular faces — every face is a triangle.
Look at a triangle. Its 3 angles together always add up to: — 180°.The three interior angles of any triangle always add up to exactly 180°.
How many EDGES does a cube have? — 12.A cube has 12 edges (the line segments where two faces meet). It has 6 faces and 8 vertices.
Shapes are classified by their angles and number of sides because: — It gives each shape a unique description we can use to identify it.Counting sides and describing angles gives each shape a precise, unique description — helping us identify and communicate about shapes accurately.
A rectangle has 4 right angles. A rhombus has 4 equal sides. A shape with BOTH properties is a: — Square.A square has both 4 equal sides AND 4 right angles — it satisfies both conditions.
A shape has 4 sides but NOT all right angles. It could be: — A rhombus.A rhombus has 4 equal sides but its angles are not necessarily 90°. It is a quadrilateral without all right angles.
An array has 5 columns and 6 rows. If you write repeated addition using columns, which expression is correct? — 5 + 5 + 5 + 5 + 5 + 5.Using columns (5) once per row (6 rows): 5 + 5 + 5 + 5 + 5 + 5 = 30.
A parking lot has 8 rows of 10 spaces. How many spaces? — 80.8 × 10 = 80 spaces.
An array has 36 squares. If there are 9 rows, how many columns? — 4.36 ÷ 9 = 4. Each row has 4 squares.
Which array has MORE total squares: 4 × 9 or 5 × 7? — 4 × 9 = 36 (more).4×9=36; 5×7=35. 36 > 35, so 4×9 has one more square.
An array is used to show repeated addition. If the addition is 7 + 7 + 7, what is the array? — 3 rows × 7 cols.Adding 7 three times = 3 rows of 7 columns each: 3 × 7 array.
A classroom has 6 rows of 5 desks. The teacher adds one more desk to each row. How many desks now? — 36.Now 6 rows of 6 desks: 6 × 6 = 36 desks.
A box of crayons has 4 rows of 8. A second box has 8 rows of 4. Together, how many crayons? — 64.Each box: 4×8=32. Together: 32+32=64 crayons.
A shape is divided into 4 parts but the parts are NOT all equal. The shaded part is: — NOT 1/4 because the parts are unequal.For a fraction to be correct, ALL parts must be EQUAL. Unequal parts cannot be named with a unit fraction.
Which list is in order from SMALLEST to LARGEST fraction? — 1/4, 1/3, 1/2.1/4 < 1/3 < 1/2. More equal parts = smaller each piece. Fourths are smallest, halves are largest.
You and 1 friend split a granola bar equally. Each person gets 1/2. If you split the SAME bar with 3 friends instead, each person gets: — Less than 1/2.Splitting with 3 friends means 4 equal pieces = 1/4. One-fourth is LESS than one-half.
Two-thirds (2/3) means: — 2 equal parts out of a total of 3 equal parts.2/3 = 2 parts out of 3 total equal parts. The top number counts parts, the bottom names the size.
If 1/4 of a garden is planted with tomatoes and 1/4 is planted with carrots, what fraction is planted total? — 2/4.1/4 + 1/4 = 2/4. Adding fractions with the same denominator: add the top numbers, keep the bottom.
A strip of paper is folded to show fourths. Which of these correctly shows 3/4? — 3 out of 4 equal sections highlighted.3/4 = 3 of the 4 equal parts. The top number (3) tells you how many parts to shade.
Why must all parts be equal when naming a fraction? — Because the size of a fraction depends on all parts being the same size.A fraction like 1/3 means one of THREE EQUAL pieces. If pieces are unequal, the fraction name does not accurately describe the part.
