Study Notes
Integer and Decimal Numbers
- -14 is an integer
- The opposite of -(-5) is 5
Inequalities and Equations
- If A = -98.9 and B = -89.8, then A < B
- The sum of 1/8 and 5/8 is equal to 7/8
Algebraic Expressions
- A = a - b - c, B = -a + b - 2, and C = a - (b + 3)
- When a = 2.5 and b = -1.2, calculate the numerical values of A, B, and C
- E = A - C is an integer
Numerical Expressions
- A = 1 - 2 × (3 - 6) - 4 × (4 - 2)
- B = 2 × [2 × (3 - 4) + 5 × (6 - 2)]
- C = 2 × 0.005 + 3 × (0.002 + 0.04) - 2 × (0.02 - 0.05)
- D = (17 - 3 × 4) × 8 - 10/(2 + 3)
Geometry and Triangles
- ABC is an isosceles triangle with A as the vertex
- AH is the perpendicular bisector of BC
- M is a point on AH
- I is the symmetric of J with respect to M
- Measure the missing angles in triangle ABC
- Triangles AHB and AHC are congruent
- Homologous elements: ∠AHB ≡ ∠AHC, AB ≡ AC, HB ≡ HC
- JHM and IHM are congruent triangles
- Homologous elements: ∠JHM ≡ ∠IHM, JM ≡ IM, HM ≡ HM
- ∠JHM = ∠IHM
