Given: δabc is isosceles; ab ≅ ac prove: ∠b ≅ ∠c we are given that δabc is isosceles with ab ≅ ac. using the definition of congruent line segments, we know that . let’s assume that angles b and c are not congruent. then one angle measure must be greater than the other. if m∠b is greater than m∠c, then ac is greater than ab by the . however, this contradicts the given information that . therefore, , which is what we wished to prove. similarly, if m∠b is less than m∠c, we would reach the contradiction that ab > ac. therefore, the angles must be congruent.

Use this data in the problem below. follow the steps carefully. round to the nearest tenth. lot 3: week 1: 345 week 2: 340 week 3: 400 week 4: 325 step 1. jim enters the data and calculates the average or mean. step 2. jim calculates the deviation from the mean by subtracting the mean from each value. step 3. jim squares each deviation to remove negative signs. step 4. jim sums the squares of each deviation and divides by the count for the variance. step 5. jim takes the square root of the variance to find the standard deviation.
