Answer:

1. ΔCAT ≅ ΔODG by SSS, Angle D equals 45 degrees

Explanation:

Triangles can be proven congruent or the same shape and size by 5 postulates:

  • SAS - Side - Angle - Side
  • ASA - Angle - Side - Angle
  • AAS - Angle - Angle - Side
  • SSS - Side - Side -Side
  • HL - Hypotenuse - Leg

To state a triangle is congruent write ΔABC ≅ ΔDEF by ________ and name the pattern. Use the letters for each triangle you see to write or name it.

To identify the pattern, place your pencil on a vertex of the triangle. Trace it and label each congruent part as you come to it as S or A.

For number 1, this would be S - S - S or SSS
