Problem Statement

In a right triangle ABCABC (∠C=90o\angle C = 90^o) it is known that AC=4AC = 4 cm, BC=3BC = 3 cm. The points A1,B1A_1, B_1 and C1C_1 are such that AA1∥BCAA_1 \parallel BC, BB1∥A1CBB_1\parallel A_1C, CC1∥A1B1CC_1\parallel A_1B_1, A1B1C1=90oA_1B_1C_1= 90^o, A1B1=1A_1B_1= 1 cm. Find B1C1B_1C_1.
