Decoding Key ATI TEAS 7 Geometry Formulas: Shapes and Spaces

Here, we break down the most important ATI TEAS 7 geometry formulas. You need to commit these to memory. Understand their application too. Practice using them in different contexts.

2D Shapes: Area & Perimeter

These formulas are fundamental. They calculate the space inside a shape. They also measure the distance around its edge.

Square:

• Perimeter (P) = 4s (where s = side length)
• Area (A) = s²

Rectangle:

• Perimeter (P) = 2(l + w) (where l = length, w = width)
• Area (A) = l × w

Triangle:

• Perimeter (P) = a + b + c (where a, b, c = side lengths)
• Area (A) = ½bh (where b = base, h = height)

Circle:

• Circumference (C) = 2πr or πd (where r = radius, d = diameter)
• Area (A) = πr²

Trapezoid:

• Area (A) = ½(b₁ + b₂)h (where b₁ and b₂ are parallel bases, h = height)

Parallelogram:

• Area (A) = bh (where b = base, h = height)

3D Shapes: Volume & Surface Area

These formulas help with objects in three dimensions. Volume measures capacity. Surface area measures the total area of all surfaces.

Cube:

• Volume (V) = s³ (where s = side length)
• Surface Area (SA) = 6s²

Rectangular Prism:

• Volume (V) = lwh (where l = length, w = width, h = height)
• Surface Area (SA) = 2(lw + lh + wh)

Cylinder:

• Volume (V) = πr²h (where r = radius, h = height)
• Surface Area (SA) = 2πr(r + h)

Sphere:

• Volume (V) = (4/3)πr³
• Surface Area (SA) = 4πr²

Cone:

• Volume (V) = (1/3)πr²h

Angles and Lines

Understanding angle relationships is vital. It helps solve many geometry problems.

• Complementary Angles: Two angles summing to 90°.
• Supplementary Angles: Two angles summing to 180°.
• Vertical Angles: Opposite angles formed by intersecting lines. They are equal.
• Straight Angle: Measures exactly 180°.
• Sum of Angles in a Triangle: Always equals 180°.

Parallel lines cut by a transversal create specific angle pairs. Remember alternate interior, alternate exterior, corresponding, and consecutive interior angles.

The Pythagorean Theorem

This theorem applies only to right-angled triangles. It relates the lengths of the sides. The formula is a² + b² = c². Here, ‘a’ and ‘b’ are the lengths of the legs. ‘c’ is the length of the hypotenuse. The hypotenuse is the longest side. It is opposite the right angle.

“Geometry is not just about memorizing formulas. It’s about understanding spatial relationships and problem-solving.”

Mastering ATI TEAS 7 Geometry Formulas: Study Strategies

Memorizing is one part. Truly understanding is another. Here are proven strategies:

• Practice Consistently: Solve many geometry problems. Repetition strengthens recall.
• Create Flashcards: Write the formula on one side. Put the shape and definitions on the other.
• Draw Diagrams: Visualizing shapes helps. Sketch the problem. Label all knowns and unknowns.
• Understand the ‘Why’: Don’t just rote memorize. Learn what each variable means. Understand how the formula works.
• Teach Someone Else: Explaining concepts solidifies your own understanding.
• Use Practice Tests: Simulate the exam environment. This helps you manage time. It also identifies weak areas.
