Why Geometry Can Be Tricky on the TEAS 7 Exam

\n

Geometry questions demand both recall and application. The ATI TEAS 7 has a strict time limit. You must apply formulas quickly and accurately. This quick pace adds significant pressure. Many nursing students find geometry challenging. It often involves visualizing shapes. You also need to perform multi-step calculations. Forgetting a single formula can cost points. Therefore, a robust understanding is absolutely vital. Our cheat sheet helps reduce this stress.

Your Essential ATI TEAS 7 Math Geometry Formulas Cheat Sheet

\n

This section details the crucial geometry formulas. These are most likely to appear on the TEAS 7 exam. Memorize these formulas thoroughly. More importantly, practice using them often. Understanding when to use each formula is key.

\n\n

2D Shapes: Area and Perimeter Formulas

\n

\n
• Square:\n
  \n
  • Area (A) = s² (where ‘s’ is the side length)

  \n

  • Perimeter (P) = 4s

  \n

  • Squares have four equal sides. All angles are 90 degrees.

  \n

  \n

\n

• Rectangle:\n
  \n
  • Area (A) = l × w (where ‘l’ is length, ‘w’ is width)

  \n

  • Perimeter (P) = 2(l + w)

  \n

  • Rectangles have opposite sides equal. All angles are 90 degrees.

  \n

  \n

\n

• Triangle:\n
  \n
  • Area (A) = ½ × b × h (where ‘b’ is base, ‘h’ is height)

  \n

  • Perimeter (P) = a + b + c (sum of all three sides)

  \n

  • Remember the height must be perpendicular to the base.

  \n

  \n

\n

• Circle:\n
  \n
  • Area (A) = πr² (where ‘r’ is the radius)

  \n

  • Circumference (C) = 2πr or πd (where ‘d’ is the diameter)

  \n

  • The diameter is twice the radius (d = 2r).

  \n

  • Pi (π) is approximately 3.14 or 22/7.

  \n

3D Shapes: Volume and Surface Area Formulas

\n

Understanding three-dimensional shapes is also crucial. These formulas calculate space occupied or surface coverage.

\n

\n
• Cube:\n
  \n
  • Volume (V) = s³ (where ‘s’ is the side length)

  \n

  • Surface Area (SA) = 6s²

  \n

  • A cube has six equal square faces.

  \n

  \n

\n

• Rectangular Prism:\n
  \n
  • Volume (V) = l × w × h (length × width × height)

  \n

  • Surface Area (SA) = 2(lw + lh + wh)

  \n

  • Think of it as a box shape.

  \n

  \n

\n

• Cylinder:\n
  \n
  • Volume (V) = πr²h (where ‘r’ is radius, ‘h’ is height)

  \n

  • Surface Area (SA) = 2πrh + 2πr²

  \n

  • This includes the top, bottom, and curved side.

  \n

  \n

\n

• Sphere:\n
  \n
  • Volume (V) = (4/3)πr³

  \n

  • Surface Area (SA) = 4πr²

  \n

  • A sphere is a perfectly round 3D object.

Angles, Lines, and the Pythagorean Theorem

\n

Beyond shapes, fundamental geometric principles are tested. These relate to angles and lines.

\n

\n
• Sum of angles in a triangle: Always 180 degrees.

\n

• Right Angle: Measures exactly 90 degrees.

\n

• Straight Angle: Measures exactly 180 degrees.

\n

• Complementary Angles: Sum to 90 degrees.

\n

• Supplementary Angles: Sum to 180 degrees.

\n

• Parallel Lines: These lines never intersect. They maintain equal distance.

\n

• Perpendicular Lines: These lines intersect. They form 90-degree angles.

\n

• Pythagorean Theorem: a² + b² = c² (for right triangles only)\n
  \n
  • ‘a’ and ‘b’ are the lengths of the legs.

  \n

  • ‘c’ is the length of the hypotenuse.

  \n

  • The hypotenuse is the longest side.

Coordinate Geometry Basics

\n

You might encounter questions involving coordinates. These formulas are essential for graph-based problems.

\n

\n
• Distance Formula: d = √[(x₂-x₁)² + (y₂-y₁)²]\n
  \n
  • Finds the distance between two points (x₁, y₁) and (x₂, y₂).

  \n

  \n

\n

• Midpoint Formula: M = [(x₁+x₂)/2, (y₁+y₂)/2]\n
  \n
  • Finds the midpoint of a line segment.
